It’s great if the engine calls for it and your operating environment allows it… In the US it helps cars meet CAFE standards. ..

I’m glad the interwebs somehow agreed with me…
Usually I do not get involved with oil threads…. Reason is… Some people think there is some magic holy grail of oil that will make their cars last 1,000,000 miles and get 50 miles per gallon….
Simply stated… I always say this…. Use the oil which is recommended for your vehicle and is API Certified… plain and simple… If it calls for Dino Oil, give it Dino Oil… If it calls for synthetic, give it synthetic…. If it calls for 5w-30, give it 5w-30…. Change it when it should be changed, and if you live in a harsh environment, use the harsh environment recommendation timeline to change oil.
There is no one magic formula… If you think there is one with AMSOIL, or Mobile one or the Walmart special then please go to Bob is the Oil guy (BITOG) and argue it until the point is belabored past recognition with so many “experts” who can tell you about the specialized amount of additives, or cleaners in their favorite “magical” oil that makes one better than the other…
Me, I am sick of it…. Tired of hearing about how someone with 300k miles on a car that is now ticking thinks that now switching to synthetic will get another 100k miles out of it…… PLEASE….
Just ranting… nothing against you… Just oil related questions press my button…
Cheers!

I would never ever use it in any vehicle unless it called for it..or I lived in Alaska or siberia!. I believe it is just used to meet CAFE requirements otherwise. I personally wouldn’t trust it unless the engine clearances were so tight that it was necessary.
ROFL!!!
Peanut oil… But I don’t put Poutine or Mayonnaise on them!!!! 🙂
Just salt and vinegar here!!! (kinda like me) Acidic!!
Cheers!

[quote=”wysetech” post=115249]Hey T.K. What kind of oil do you cook fries in? :silly:[/quote] Ahaha!
I believe Toyota started recommending 0w20 in the Prius not only to allow good fuel economy but in a Hybrid the engine has to start and reach a high rpm on short notice when not on battery power and it needs instant lubrication. The 0w20 provides that.

[quote=”ToyotaKarl” post=115259]Actually FWIW, since around 2011 Toyota has switched many of its vehicles to 0w-20….
-Karl[/quote] As a GM technician, I know GMs new truck engines also use the stuff. Its a full synthetic dexos oil and it might as well be water. Other than CAFE standards is there any reason they use the stuff? The parasitic drag on the rotating assembly can’t be that different than 5W-30.
Part of the issue is all the crazy insane tight clearances that the newer engines have in place. I’ve seen cars use 0w20. 0w40 (our Beetle for example). The idea is to have a light enough oil to get very rapid oil pressure/volume and not having much drag on the engine.
Best bet is always to use the manual and recommended oil(s). And if you have an ‘exotic’ car? The maker will list an exact spec listing..such as, 500.00 or 501.00 (or some such number) If the oil you run meets the spec as per the maker? Should be fine. Just read the bottle/can and look at it against you service manual. And you can use the oil chart that almost each maker has in the front of their manuals.

Mobile 1 did a big add campaign about a year ago about their zero weight oil how it belonged in everything. They acted so impressed with the mileage increases. The differences were VERY small, so small, that I ran that against my current MPG and the increased cost of the oil….guess what? The tiny bit farther that my car would go (not much) per gallon was 1/2 as good as it’s cost increase.
Paying for more…getting less.
Note: I’m an avid user of synthetic oil, feeling my car running smoother, happier, more efficient, and more powerful, so this isn’t from a guy who doesn’t appreciate fine oil.
And by the way, I like my fries, fried in Canola oil. 🙂
