Just switched to Amsoil - Toyota Yaris Forums

There is no correlation between brands of oil and engine temperature. All your findings are anecdotal at best, and really are not enough to draw any conclusions.

Any college grads out there?!?

Also to the OP: is your tranny automatic? If so there is no need to change out the fluid until 100,000 miles.

Although AMSoil is perhaps the best, it will not cause your engine to last much longer then had you used the cheapest Walmart synthetic oil. With the cheapest synthetic oil, your engine will still last 300,000 miles. In addition, the gains in MPG are 1% to 2% at best.

Also, using AMSoil is only economical if you extend your oil changes to 10,000+ miles or more. Otherwise you are just wasting money and fooling yourself.
