Amsoil synthetic oil around here for faster cold weather cranking and oil pressure sooner.
Cool. Thanks for the responses.
PS. I also use Fram oil filters in my cars and never had an engine problem.
I have a more than 30 years of quality assurance background. Definition of quality= meeting the specifications. Exceeding the spec does nothing for you except cost you money. Regulations for grades of oil set the standards the oil must meet for each classification. Exceeding those specs does little for you if you change your oil as specified by the manufacturers. If however you want to run 10K miles on your vehicle when the manufacturer says change at 6000 or 7500, you may want to use the super oil.
I just may switch to Mobile 1 when I run out of T6 if the price is close. I bought a bunch of it on sale months ago but cant remember the price I paid. Still got about 4-5 gallons. I have some T5 for my truck an a lot of T6 for the tractors, JD lawnmower and Kubota RTV.
I am all for using top brand motor oil but dont put any stock in small company claims of being super oil and can run in a car for 100 miles after loosing all the oil. I think about any brand name oil will give acceptable results in normal operating conditions, its when we go above normal that causes the engine failures when oil breaks down under load and extreme heat. Keep an engine cool and not too heavily loaded and just about any oil will work
yup.. on my old dodge truck that got 3000 m oil changes every couple months, and new fram, stp or supertech 2.50$ oil filter and 5$ air filter each time... plus walmart oil... I have a feeling that the oil was near as good going in as coming out... truck never leaked or used a drop.
the yukon probably don't even need a change.. ever. by the time it hits 3000m I've already added a few quarts out of 5 :(
I should just change the filter on it every 3 months and call it good and just keep the oil topped off...
now the powerstroke that gets high rev for long runs pulling a trailer.. that one I'll squeeze the wallet for some valvoline ultre premium blue full syn 5w40 if only fo rthe heat / turbo issues.. and since the truck runs at such a high rpom to hit interstate speeds..e tc.
You guys are lucky... Up here M1 is twice the price of Rotella, no way I will ever pay that for an Exxon product!! It is not that much better then Rotella!!
