Just did my first 1k service at the dealer, and found out that Mobil 1 was used (as shown on the invoice).
But... Mobil 1 does not make 5w40 at all!
I am going to change the oil myself this weekend, but don't know which oil to use.
Havoline 5w40 is listed on the manual, but I have had no previous experience with them and they are pretty hard to find.
I have been using Castrol SYNTEC and GTX on all my cars for the last 8 years and are very happy with them. (Once drove the car for 30 mins without coolant in it, and the SYNTEC protected the engine pretty well - no blown gasket, no damage at all)
MOTUL has an ester based 5w40 synthetic oil and said to stand up to really high temp (which our 2ZZ-GE sees all the time in the back) but at $26 per half liter.... for a Toyota engine??
help please
