does anybody think it would be bad when i switch over to synthetic at 10k miles to use mobil ones 15w-30 it says on the bottle its for high performance engines which i think our engines are. i know we are suppost to use 10w-30 but i don't really think it would hurt our cars. what do you people think?

 

USE 10W30....use what those Brilliant Japanese Engineers reccomend.....they know what is best.

10k miles is ok to switch to synthetic. When I hit 6k miles(10k kms) I will be switching over.

Mobil 1 10W30 Synthetic

Simple

 

what about mixing (3)10W-30 and (2)15W-30 together and get 12W-30?

 

i really don't think it would hurt putting in 15w-30 i mean what problems could there be?

 

15W-30: I don't think it would hurt, in cold climates it just takes longer for the oil to heat up. 10w-30 is just a all year round oil.

 

i live in south fl its redic how hot it is!!

 

it is pretty hot in texas also. recently a dry- hot -heat.

 

i think it wouuld be a good oil for hot weather zones

 

Why are you so insistant??? Honda says to use 10W-30 and you say that 15W-30 should be O.K.. Do you know something Honda engineers don't? If you use that oil, your warranty goes out the window. Plus, I saw somewhere here that a new engine costs $10,000.

 

If you drive in hot weather and at high rpm 10W-30 will damage your engine.
