I read here that a good dino will go 5K OCI, a full synthetic goes 10K+, and Mobil 7500 synthetic blend 7500 of course. Why then do I see Trop Arctic, Motorcraft and Kendall blends only referenced as 5K OCI? Shouldn't they be good for 7500?
I don't have an oil life monitor, I primarily refering to 5W20 in a Civic. Though there is not much price difference, I don't understand why these blends aren't being pushed a little farther than would be a Havoline or Castrol Dino.
Not at all, I'm just seeking opinion on which oils are best suited for the longer OCI. With Mobil 7500 and others going the distance, I'm unclear as to why I don't see more 7500 OCI's with the Conoco blends available at very competative prices.
liability...even on the mobil 7500+ oils they recommend you stick with the manual's recommended OCI's and then they mention that they will guarantee the oil for 7500 (they still prefer you to follow facory OCI's of course)
And the other thing is Conoco doesn't want to pay for any small chances of a car breaking down due to oil related break downs like Mobil does (they have to send out their own mechanics, do a UOA, etc it cost money)
My question isn't why isn't Conoco promoting 7500OCI, but why aren't there any BITOG'ers pusing it to that point. Havoline doesn't market a 5KOCI, yet it is the norm here. It would seem that a highly respected synthetic blend should go to 7500. Or perhaps it isn't superior to a good dino?
The low-static way for an oil blender to do business is to just do whatever the carmaker says.
Pushing a long OCI like Amsoil/Mobil 1 do requires user education and really only makes sense if it makes you more money. On top of this, there is very real liability here... if you were pushing extended OCIs and ran into a situation like the Toyota sludgemonster (again) you could wind up with a class action suit against you because a consumer trusted your oil and it failed them in an abusive situation. Even if you win, you'll be paying through the nose to your lawyers.
