Interesting vid.

This should be an interesting topic................:rolleyes2:

 

GM Dexos.

 

Dexos or Dexos1 Gen2?

Dexos is a GM spec. Similar to the ones German automakers use. They can't say what brand to use, only one that meets their specifications.


The Gen2 is supposed to minimize valvetrain buildup on DI engines.

 

I am looking at 0w20 oils now for my new 18 Civic Si, A dexos1 gen2 with the best HT/HS, and the lowest Noak. Oil company's now don't show all the specs they used to in there PDS. Making it hard to pick an oil! Today's oils are all so similar in the way they perform that it really doesn't matter which oil brand you choose. So pick what ever is your favorite brand. The best oil i have found is Redline 0w20, but it isn't API rated, or Dexos1 Gen2.

 

Just bought some Honda oil 0w-20 full synthetic. They actually sell 2, I got the cheaper one. Also use Castrol 0w-20 full synthetic because it's readily available.
Doing Service A III bought all the parts from Honda. Prices were great! I was surprised. Roush Honda in Columbus, Ohio.

 

Better than $25/5 qt jug of Pennzoil Platinum 0w20 ? I try to use either the PP or Mobil 1 0w20 (sometimes 5w20, but always full synthetic) which is usually even a few dollars cheaper. I also bought a 12 pack of Fram Ultra-Synthetic oil filters online for a decent price. That filter seems to rate extremely high in most of the oil filter tests that I have looked at. That cut the cost to around $7/filter.

so what do the Honda dealers use? I assume they all use the same oil on our CRVs...

??Just bought some Honda oil 0w-20 full synthetic.

i'm a long way from an oil change - and interesting responses so far.

If you get the cheapest oil change they probably just use bulk conventional oil from a drum. The synthetic blend and full synthetic sold by Honda is made by ConocoPhillips, and can also be bought under the Phillips 66, Kendall, and Ford Motorcraft brands.

 

I just buy price (or what is available) at Wal-Mart for a 5 quart jug of name brand synthetic oil. There is really not a lot of difference between the common ones (Mobil 1, Castrol, Pennzoil, Valvoline, Quaker State). My preference by a slight margin is Valvoline though because it seems to be the least volatile / lowest consumption in a high mileage engine. 0w20 high mileage Valvoline was giving me less than 1 quart consumption in a 5K severe service interval, while the 5w20 Pennzoil Platinum high mileage that I bought a bunch of with a rebate has been closer to 2 quarts every 5K miles.

 

Same here. The supertech full synthetic is what I have been using too. Seems to be good oil. Stays pretty clean.

 

Honda dealers are free to use any bulk oil that meets Honda’s spec, which is basically an API certified 0w-20. My Honda dealer uses Total, my Acura dealer Castrol. Oil changes are a loss-leader for dealers so they will use the most economical choice available. Ask your dealer what they use.

I suspect very, very few Honda dealer use Honda oil for normal oil changes.

 

Really? I sure didn't know this. Now you have me curious and I'll have to dig out the last service invoice and see what it indicates. I always just assumed it was a Honda oil.
Thanks for the info.

 

All our Hondas use 5W20 or 5W30 Pennzoil Ultra (on sale many times a year and rebates $10/5qt) bring price down to around $14/5qt

Why ?

For one reason, watch this savagegeese video at around 16 minute mark

 

Great price for a super motor oil, and, it also has that low oil volatility. Strange the way that vid spelled 'volitility'.
Sometimes I forget to mail in the damn rebates.
After I finish my supply of Mobil 1, i will start using Pennzoil Ultra if it goes on sale next year.
I have seen that vid before and I think it is very informative.

There’s an awful lot going on in the sump of an automobile engine and plenty of atomized vapors of all sorts waiting to be scavenged by the PCV system. But I suspect the amount of these vapors that represent true evaporation of engine oil is a very minor component. Exhaust gases, evaporating water and raw fuel are the primary elements.

Why? Well, the Noack test is run at a temperature (250 C) sumps just don’t reach. There are owners everywhere that credibly report their engine has no oil consumption. If oil was at Noack test temperature, even the best oil would be using 5% of its mass each hour which would equate to absolutely horrific oil consumption. And if oil evaporation were really an issue, we would have no reports of negligible oil consumption.

So, I wouldn’t fret about Noack much (current values are hard to get in any event). Modern standards like dexos1Gen2 and the upcoming SN Plus have Noack standards that satisfy OEMs.

 

Either way, I barely use 1/2 qt in 6k miles and I have over 185k miles on it.
Pennzoil Ultra is highly rated for lubricating and cleaning.
Hell, for under $20 while on sale, why not?
Still, if Mobil 1 is on sale, I use it.
No sense fretting about the Noack standard on my '03.
Thanks,

PS: Why settle for 10th best when one of the very best is such a deal?

 

You do realize that the tests in the video are from 5 years ago. Formulations have changed considerably since then, largely because new standards (dexos et al) have required lower volatility.

And the Ultra you have been using has changed a lot: in 2013 Shell’s GTL plant in Qatar was coming on stream and it was used heavily in Ultra. This is no longer the case and Ultra was in the 10% volatility range the last time I checked.

There are likely a couple oils out there with ultra-low Noack (Redline and Amsoil, perhaps). But be careful: these oils may not be API certified, which is a warranty concern and also may not meet dexos1Gen2 standards, which is important for a TGDI engine.

So again, I wouldn’t sweat it too much. Major maker dexos1Gen2 0w-20s on the shelves at WalMart (Mobil1, Pennzoil Platinum and Ultra, Valvoline, Castrol, etc.) combined with a sensible oil change interval will do just fine...unless fuel dilution intereferes, but that’s another story.

Very good read if you are interested in motor oil in engines.
If you have a flat tappet push rod engine, it is really interesting why some of the top rated synthetics may not do the job for you.

I religiously use Castrol GTX in both my cars, the 98 BMW Z3 has 117,000 and the 2003 crv has 175,000 miles. I usually change oil every 5000 miles. I bought the CRV with 8000 miles on it in 03.

2017 with 45K 0-20 full synthetic

bought it last year with 40k
no problems. CVT takes getting used to on downhills

my GM's kept puking so bu-bye Chevrolet
