“Toughest” 0W-20

Problem is it is dependent on a number of factors like engine, temperature, fuel type, driving pattern, OCI etc.

So what is the best most toughest oil for one person isn't the same for another. It's why BITOG exists so we can discuss it!





Good point. One person may have a older engine with port fuel injection while another will have a TGDI engine. So there are some considerations.

10w-30 will work well in just about any application that doesn't require extreme cold starting. My .02

Extremely well said StevieC and PimTac.

Remember, you have an 8-QT sump IIRC. Cost is a consideration, and so is your warranty, so I'd steer clear of boutique oils and anything thicker than the recommended spec's. So I'd take advantage of rebates in season...

He doesn't do "push-ups".....He does "earth downs"! Chuck Norris is the only movie star I've ever met in person (worked on his car)....He was a Fort Worth regular for years with Walker, Texas Ranger. Really nice guy!

We run 0w40 synthetic in all the Ecotec3 engines we put TVS1900/TVS2300 superchargers on, A 10w30/5w30/0w30 WILL NOT harm these engines.

Separate question; when switching to a heavier viscosity oil, your oil temps will increase, correct? So if that’s the case, then wouldn’t switching to a heavier viscosity slightly negate the change? Due to the oil being hotter, and the hotter the oil gets the thinner it gets.

I remember those too, and I was a firm Mobil-1 believer. After reading those and the associated comments I switched to Pennzoil Platinum and haven't looked back.
I also thought, even though this has likely been debunked, that with the Pennzoil Platinum, my truck ran quieter and smoother.

Nowadays, with so many quality oils on the market, I don't you can go wrong with most of them but for the price I can usually find PP or PUP, I will like stick with it.

No, the difference in temp is minimal.

Id go with Pennz Ultra, M1 AFE or M1 EP. AP isnt worth the cost.

Temp increase ? ....... in some cases if perceptible , but not all cases.
If ever there is temp increase, it's minimal as per Overkill. I would speculate generally, a figure of 1-3*C increase.

Hotter (or warmer ) oil of thicker viscosity grade oil gets thinner than cooler oil of lower viscosity grade ?
Not true in almost all of the cases in terms of operating viscosity.
A 'hotter' xW30 at say, 105*C has typically higher operating viscosity (and hence MOFT) than a 'cooler' xW20 at 100*C.

So is xW30 vs xW40 or xW20 vs xW40.

The newest lists gives #1 position to Mobil 1 0w-40 FS.

 

[dblshock]

minimal fuel penalty vs. elevated protection with 0/40, no question here.

That is something to consider.

I don't know about that. Norris oil is getting on a bit and you would need to see if it has enough calcium in it so it don't break something structural.

True, but only (as you say) slightly hotter with the thicker oil, obviously never enough to make it thinner than a thinner grade oil.

QSUD 0W20 and Valvoline 0W20 full synthetic with Maxlife technology always seemed to run well in my engines. I also use the Valvoline full syn with Maxlife tech in the 5W30 for my Lexus and it runs smooth as silk.

Depends on what controls oil temp?

Air cooled engines w/o oil cooler, maybe the logic holds.

Water cooled, the few degrees rise in the bearings will not offset the viscosity that much. Also depends on bearing clearances and side leakage rate ...

Was at Wal-Mart last night looking at my options for my new GMC Yukon Denali with the 6.2L V8 in it that calls for 0w20 (essentially the same engine as in the Corvette that calls for 5w30,) and I saw this Mobil 1 0w-30 AFE product. Same GM Dexos 1, GM 6094M, and API CF specs. Being in Central Texas I'd like a little more protection in the Summer months, and I might consider this over the 0w-20 if I do in fact decide not to go with 5w-30.
