Since I have a High Mileage Car I decided to use High Mileage Oil.
I'm gonna use Castrol because it has a low phosphorous content
and that will help protect the emission system.
I do not want my Catalytic Converter to go bad.
Better to do this than risk a failed CC.

Curious,
Was your CRV using oil and that is the reason you are switching to a high mileage oil?

Nope, doesn't use any oil.
I'm switching due to age of car and because of stated reason above.
CAT Converters cost a lot of money.
This formula oil helps prolong the life of the converter.

This is odd to say the least.

The difference in levels of any modern engine oil aren't even worth a mention as they are all extremely low as required be regulations put in place pushing 20 yrs ago. Only cheap oil or using conventional oils meant for older engines will cause any converter issues. Choice of fuel used makes far more of a difference than the trace differences in engine oil

If using conventional oil and going as low as possible there will actually shorten the life of your engine substantially. Premature wear is a very noted issue.

This is why synthetic oil has taken over. Because it performs better without the additives you are worried about.

FYI Castrol is not very highly ranked in tests compared to the more highly regarded brands.

I'll reconsider, do a little investigating since I like Pennzoil the most.
I liked running Pennzoil in my Goldwing, it always made the engine
run very quiet, quieter than any other oil I used.
Thanks for the advice.

Unless something has changed, "high mileage" oils have seal conditioners added. Seal conditioners will make the rubber in the seal swell a little. If they aren't leaking, this could accelerate seal wear. I wouldn't use anything with a seal conditioner added unless you are finding small leaks. It could help with that. Otherwise just run a good quality, standard oil and you should be just fine.

I've been using Walmart SuperTech oil in all of my cars for years with no problems. I understand that some of the major brands offer online rebates which makes their prices more competitive. I'll look for the rebates next time I change my oil.

Two of my current cars have over 160,000 miles and I don't use high mileage oil in either of them. My old Civic was pushing 300,000 when I finally junked it for convenience. It had no leaks or engine problems and I always used the cheapest brand available. As long as you use the proper grade of oil, and change it at least as often as recommended you will be fine.

How dare you recommend Walmart SuperTech motor oil!! :(
I sure hope you don't use Walmart oil filters or, God forbid, Fram oil filters. Good God, what were you thinking???

Overall, Congrats for posting that!!!
The major point is to use the proper recommended oil specs (API and wt), decent oil filter and change it at 'least' as often as recommended !!
I use the Synthetic Oil because it is said to have quicker lubricating in very cold weather upon first startup, better lubrication at high temps, better engine cleaning and possibly a little better mpg.

Some here get so damn wound up on which brand oil, which brand oil filter, which brand of ?????
Many say to "Don't use the Honda A02 oil filter, only the A01 oil filter". IMO , both of them are lower in filtering efficiency quality compared to most other brand names, even the Fram Tough Guard. :)

Thanks,
Buffalo4
