Thanks
The big question is WHY?
Not going to gain ANYTHING.
That would be one of the last things I would do.
Toyota gives you a 5 YEAR 60,000 mile engine warranty. Why screw with Toyota and your engine?
Interesting how people want to spend more $$ and not gain a *single* thing...

I live in Phoenix, AZ and wondered whether the 30 would protect as well as the 40 in the Phoenix summers. I asked if I could continue to use the 5W-40 I had been using with my old car. The universal answer was "no". The oil company engineers all told me that if the internals were sized to accomodate a 5W-40, the manufacturer would have specified a 5W-40 and not a 4W-30. They all said it is okay to go to a lower number, but never a higher number.
PLEASE tell me who these "engineers"
work for.
I want to know what oil company to stay away from.
Really, I want to know the name of the oil company.
