If you were forced to use 1 motor oil for life....

Quaker State. SOPUS at a discount. Can't go wrong.

Shell Helix Ultra 5W-40, that way if I win the lottery and buy a Porsche or Ferrari then I'm still running an approved oil. It meets the SN & A3/B4 spec of my present 4-cylinder Opel family car too.

This. You need to think of all scenarios, all conditions, all use cases, all engines. M1's 0w40 would cover them all.

I'm 72 and have used M1 oils for 39 years, and plan to use it well into infinity.

Mobil 1, to infinity and beyond!

 

[Mr Nice]

Any quality Dino oil like Havoline or Pennzoil.

 

[Triple_Se7en]

Pennzoil

 

[demarpaint]

Times change, if I were "forced" to use one oil only it would be Pennzoil. Until something I feel is better comes along.

M1! OH! I already said that.

And even if you didn't, I think we would all know anyway.

Have a good day.

Oil wise, many here are like a ship without a rudder and drifting aimlessly in the oil isles of WM, always searching, never finding.

The way these 0 weights like 0w-20 and even 0w-30s are performing, in addition to the new Dexos 1 Gen 2, something along these lines namely the 0w-20 since I am using a generic branded (honda via Phillips 66) version and not experiencing any of the burning I experienced on older speced formulations, even with paltry 5k OCIs. The 5w30s and even 10w30s of older formulations never rectified the .5 qt of consumption on meager 5k OCIs on new car, like these 0w-20s are doing for me. And I'm not even talking about using the elite in this weight like the mighty Mobil 1 Advanced Fuel Economy 0w-20 that everyone is smitten over here at BITOG (molly shannon arms raised!). So far, just using the generic branded 0w-20s, no consumption at all, no future deposits that I can foresee on the intake valves either! Why go back in specs, if you know what I mean (and alluding to)

I'm like a kid in a candy store ........Oooooo, what should I try next?

But to be honest, regular M1 5W30 would do most people for most applications. I'm surprised it's not used more.

Over here, we can get a full synthetic Castrol Magnatec 5W30 that is API SN and Euro A3/B4, that should work in just about any application short of special OEM specs. And even then it will probably work fine to with a reasonable OCI.

Royal Purple

 

[artificialist]

I use the Castrol brand.

My dad used to have a 1987 Hyundai Excel and he used Castrol GTX 20w50 exclusively. He put 110,000 miles on it before trading it in. Nobody at the dealer had ever see a Hyundai Excel live that long.

If you can formulate an oil that partially makes up for a badly designed and built car, imagine what good it does in a car that was designed well.

There is one rule, however. I never use Castrol 5w40 because it is the only synthetic oil I have seen that leads to engine varnish. I have 0w40 in my car.
