This is definitely one subject that we have beaten to death here on the forum. Are there better oils than M1? I believe that there is, but as several members have said above, none of us are really going to tell the difference. I think you will look long and hard and pay a lot more money to do better than M1.

I wonder if anyone uses the search feature before they ask this time old question.
Every few months this surfaces. It will never die.
Bottom line is that difference between premium syns is so thin (no pun intended) you can't tell the difference.

There really is no comparison between petroleum based oils and synthetic oil.
Synthetic oils do not break down in the familiar sense. That is the reason why Amsoil can be used for up to 25,000 miles in an engine with only filter changes every 5,000 miles and topping off the level.
Fleets (buses, trucks, cabs, ambulances, police cars etc.) can save many thousands of $$$ by using synthetic oil.
On an individual basis (Vette owners like us) there is no money saved. Unless you wish to count "peace of mind". Just knowing our vehicles are being protected with the best possible oil on the planet is comforting to me.
I owned an auto & truck repair shop and saw firsthand what kind of damage could be caused by not changing one's oil. It was not pretty. The money involved was enough to make you sick.

I agree. A friend of mine is a tech at a dodge dealer, and about 4 times a year, some moron will come in with a car with 30k miles on it and a siezed up motor, and wonder why... it's because the oil had never been changed.

I grew up before there was Jiffy Lube. Now there really is NO excuse for not doing the minimum maintenance involved. Even girlfriends of mine have enough sense to have their car's oil changed. 
Having a forum like this one certainly reinforces what needs to be done to these Vettes. And to the other vehicles we own.

Mobil 1 and Amsoil are more alike than different. Both PAO based with some Esters. Amsoil uses ExxonMobil PAO's. IMHO, the absolute best oil for high performance applications in performance cars is Redline oil. No doubt about it in my mind. Very few people have a good understanding of motor oil. A common example would be "oh my oil is dark, I guess I should change it." Oil gets dark when it's doing it's job by removing contaminants. Just pick an oil that meets the GM spec. Pennzoil Platinum is actually a good oil for the money right now.

I have been using the BMW 10W60 synthetic oil that Castrol makes for the BMW M5 engine. I like it so much in my ZF 6 speed trans that I thought I would see how it fared in my engine.
Oil pressure is up substantially at all temperatures.
When it is time to change it again, I will use it again.
I will keep you guys posted on how it works.

I beg to differ. I am giving up NO horspower.
The fact that the oil has the 10W designation does not mean that the oil is thicker. This is a myth.

Are you saying that oil that is dark, even black, shouldn't be changed? Or are you implying that it should be changed before it gets dark? Clarification, please.

That particular oil also sells for $12-$16 a quart.
For that kind of money it should change itself.

Did anybody consider the fact that high oil pressure can result from flow restrictions? Which would you rather have, 30 PSI and oil on every surface, or 60 PSI and oil that only gets to the pressure sensor?
Very basic fluid mechanics will tell you that the mesaure of an oil / filter should not rely on pressure alone.
