Hi there fellow CRV neighbors,

Well, here is another post asking which is best to use: motor oil or synthetic oil. I have read the many posts and there are different opinions about this topic. I just had my oil changed and I have only used motor oil so far as well as the previous owner. I have my oil changed every 3,000 miles. Living in a very hot climate this has been advised and I follow it. My conversation with the mechanic was such that he felt for the next oil change and thereafter to be synthetic. It will be better for the longevity of the car. Then I was told I would only have to change out the oil every 5,000 miles. I have a 2007 with approximately 123,000 miles.

My question is: Since I have more miles now would it indeed be better to switch over to synthetic oil? By the way, I intend to keep this car for as long as possible. I may go before it does. :)

I am sure this is a never ending topic. Thank you for all replies.

Here we go again. There’s everything and everyone in this spectrum.

Some change every 3000 miles and swear by it. I have been changing my fully synthetics every 9600 to 12.5K miles for the past two decades (cold and dry climate, I manage about 8-10 cars on average at all times) and never had an issue with oil burning on having to add any between changes. The highest mileages have been 190K, still tight with no rattles or oil burning.

Your 2007 CR-V has a Maintenance Minder feature which reminds you when service is due.
One of those function is an Engine Oil Life Display, that includes the ability to display the Engine Oil Life % remaining.

You really should read that section, as the idea of changing the oil every 3,000 miles is very outdated.
While my first CR-V, which was a 1999 model, didn't have the Maintenance Minder function, there was a section in the Owners Manual that described Normal and Severe driving conditions, and then had a Normal and Severe maintenance schedule. Even under the Severe schedule the oil change interval was 3,750 miles, while "Normal" was 7,500 miles.

The Owners Manual has a section on oil viscosity and type. The 2008 Owners Manual that I'm looking at says to use 5w-20, and also says:

Synthetic Oil
You may use a synthetic motor oil if
it meets the same requirements
given for a conventional motor oil: it
displays the API certification seal,
and it is the proper weight. You must
follow the oil and filter change
intervals shown on the information
display.
So even if you use synthetic oil, Honda says you still have to follow the Maintenance Minder.

Thank you for your comment.

I no longer take my my car to the dealership. My main mechanic told me it was best to change the motor oil every 3,000 miles. My mechanic isn't trying to sell an oil job to me. I have now used 2 other garages and they say the same thing because of the intense heat.

I have read the manual section on oil viscosity. I was just curious if switching over to synthetic would be a good idea.

Thank you for your help!

I understand that you trust your mechanic, but do you also trust Honda?
They designed and built your engine, and they designed the Maintenance Minder system to help you take good care of it.

And I will tell you that almost every time I take my CR-V into the local Honda dealer for a service visit, usually an oil and filter change, but also transmission and rear differential fluid, the service writer always tries to sell me services I don't need. And remember that the shop you go to, whether an independent shop or a the service department at a Honda dealer, makes their money by selling you more services.

And I'm curious about the "intense heat" comment. Yes, I know that Texas is going to be a bit warmer than it is here in Tennessee, but the air temperature really has nothing to do with the engine operating temperature. Whether it's over 100 F in the shade, or there''s snow and ice on the ground, once you're driving down the road and your engine has warmed up, the engine temperature is going to be around 200 F. And if the "intense heat" comment is about the engine operating temperature we're back to Honda knows your engine better than your mechanic.

When you have some time, the link below will help you to better understand motor oil facts, myths and provide you with way more valid info than opinions. One of the most important facts you can take from Dr. A. E. Haas's article is "better oil flow equals better lubrication" and the lower the 1st number (0WXX vs 5WXX), the better the oil flow at less than operating temp. Happy reading.

Do NOT TRUST MAINTENANCE REMINDERS.

They are there for those that are too lazy and incompetent to properly care for their vehicle. So they create those simply to make sure the vehicle survives till warranty expires.

I thought long and hard on this, too, and in the end, I decided to stick with conventional organic (liquid dinosaur) oil and not synthetic. First, my engine has about 93k on it, all on conventional oil. Second, synthetic oil tends to leak through gaskets and seals more easily, and I don't like oil leaks. Third, synthetic is more expensive. Fourth, I prefer fresh oil every 3k miles, as it has always worked well for me, and I wouldn't trust synthetic to last longer between changes. There is no definitive proof that it does last longer or is better. Fifth, yes, living in a high-heat climate is different, and warrants extra consideration in all things maintenance-related.

And, no, Honda is not more trustworthy than your ace mechanic. Also, never go by the maintenance minder or owner's manual. Honda wants to sell more cars, and they will always point you in a direction that leads to that point, using any and every trick possible. They also want to smoke every dime possible out of your pocket at any and every opportunity in between, in maintenance and repairs. There is no profit or future for them in advising you the best ways to take the best care of your car.

I'm perfectly okay with those who choose synthetic, but I think it's a choice better made when a car is new. So I'm sticking with conventional, and I would advise the same for you. It's less expensive, better proven, and is what your car is already used to.

To each his own but FYI there is A LOT OF definitive proof synthetic is better. Reason why almost all new vehicles require it now. As well as any mechanic worth their paycheck are all in agreement with synthetic. There are alot of later model vehicles using conventional voids the warranty. The last few years most manufacturers have started requiring synthetic.

Now no way in hell I would run it to 10k miles between changes (that's just ignorant and pray for the poor sole who buys it used) but the cost of synthetic is balanced by the time it lasts compared to conventional.

So if it works for you running conventional (and your vehicle allows for it as I believe all but the new Vs do) and changing more often, go for it.

Fully synthetic has been a requirement for over 20 years in Europe. My first new car (96 Escort) had 0W-20 Mobil 1 from the factory and every 9600 miles from that moment on. There's gazillion miles of experience with no issues.

Your choice of course, but your conclusions show that you need to do more research if you really want to understand which is best. Still, the recommended oil is sufficient.
Hot ambient temps are not the deciding factor in engine operating temps. However, they are a factor in how heavy the oil can be when first starting a 'cold' engine.and still get early lubrication. It is said that most engine wear occurs upon the first minute or so of starting a 'cold' engine.
And NO, synthetic oil does not cause leaks etc, not in this day and age. Do some research yourself and quit believing old wives tales, etc.
In conclusion, many have had their Honda engines run well over 200k miles with almost no oil loss between changes using 'Dino' oil.
Me, I like to keep it clean but most say that is not a good indicator that it needs to be changed..
Still, I use full synthetic 0w20 in my Odyssey and change the oil and filter around 6k miles. Once in a while, if the oil looks darker in under 3k miles, i will just change it again, but not the filter. I will change the filter the next time, regardless of the mileage. Still, I only drive less than 10k miles a year.
A quality synthetic oil is proven to protect better than conventional oil under low temp and high temp extremes.and to give quicker protection under first start. Is it worth it, I don't know but I feel better doing it.

Do what you want, since changing the oil as often as you do, will most likely be beneficial for you as long as you use a the proper viscosity and API rating.engine oil.
Synthetic oil also CLEANS better, according to most reports I have read.
Don't worry about more engine leaks if you switch to a quality full synthetic oil and don't buy the high mileage type UNLESS you are already having an oil leak problem.

Context is important here... even though it is a different thread from our last discussion.

Your signature puts you in a 2007 CRV... so of course you can use non-synthetic oil and heavier weight oil then 4th/5th gen CRVs. You would NOT be doing so with a new CRV... for reasons already expressed by others.. not to mention Honda specifications (not recommendations... specifications).

I have to give you credit for consistency in your use of conspiracy theories though.. between this thread and the Fatality Data thread. :ROFLMAO:

In my view... if you trust your mechanic.. you listen to your mechanic. :) If he/she recommends moving to a synthetic..... I see no issue.

Internet opinion on the other hand... if presented and it does not make sense, nor is it backed up with actual supporting data...... best side with the mechanic.

There are a lot of pluses for going with a modern synthetic oil (particularly in harsh conditions) .. and the only possible downside I know of is some reports of otherwise tight seals beginning to leak on synthetics... but that is probably something to discuss with your mechanic if it is a concern to you.

Guys, I am not dissing synthetic, and in fact I have had quite positive results with synthetic in my motorcycles, such as my FZ1. I also know it is required in some vehicles, though I think much of that is hype and not necessarily scientifically proven need. However, in this thread we are talking specifically about Gen3 CR-Vs with around or over 100k miles on them, which have used conventional oil up to now. So comments related to later models have no bearing here. Get it? Bearing? Sorry, I had to do that.

If I was running a new model, I would use the synthetic oil specified. But I'm not and never will be, so no need to go into that arena. If I total my '07 tomorrow, I will go look again for an '06 with a 5-speed, or barring that, another Gen3. Whatever, I'll stick with conventional oil. You may choose to advocate for synthetic in these cars if you like, but I will stand by my decision, and I think it will work out just fine, thanks. Does that make me old school? To me it's just common sense.

The USA Gen V manual says synthetic oil may ALSO be used.......as if 0W20 is even offered in conventional. It's not, but who's to say 0W20 conventional oil will never be offered.

Other countries show 5W30 in the Gen V manual and we all know 5W30 is offered in both conventional and synthetic. I do not see anywhere in the USA manual that synthetic oil MUST be used in the Gen V CRV. Maybe I missed it.

I am not familiar with the 2007 CRV manual.......I suspect it does not say synthetic oil MUST be used, as the 2017 manual says.:unsure:

My Gen4 manual says 0W-20 for European models. Others can put pretty much anything there.

I think with Honda, it's always more about the industry specifications for the oil to be used, rather then synth vs non-synth. Of course for engines where they specify 0W20.... it is by default synthetic, or perhaps a blend. I doubt any oil producer is going to bother making a non-synth 0W20 oil so the debate will likely never take place for 0W20.

Other countries show 5W30 in the Gen V manual and we all know 5W30 is offered in both conventional and synthetic. I do not see anywhere in the USA manual that synthetic oil MUST be used in the Gen V CRV. Maybe I missed it.
Interesting. This may be just be different engine configurations in different countries.. or it could be something to do with mpg and emissions standards be more relaxed in some countries.

All fair points and expressed well in the context different generation CRVs.
