I've looked at the Honda UK oil recommendations for my car (2001 Prelude 2.2L VTEC) and they recommend 10W-40 to be used in this engine. Honda Canada recommends 5W-30 for the same engine. Obviously the bearing clearances are not an issue with 10W-40 otherwise Honda UK would not recommend it. Apart from a slight decrease in fuel economy and power, are there any disadvantages in running 10W-40 (Amsoil 10W-40) in this engine? Would the engine run hotter or cooler with a more viscous oil? I'd only run it in summer here in Toronto, going back to 0W-30 in winter.

Also, is it OK to keep changing oil viscosities? I've heard it's best to choose one oil and stick with it.
 
Here's a close up pic of the Honda branded oil for cars they sell in Asia.

I wouldn't really recommend a 10W for car that will be operated in Toronto (I'm sure Patman will disagree

). Maybe a 5W40 weight might be a good alternative during winter climates.

It depends on whether it's a dino or syn. I'd rather have a 10w40 syn at -30F than a 5w30 dino in cold temps.

For my pushrod V8 I think 10w30 is fine, it starts up no problem in 0F weather. I wouldn't recommend it for a DOHC engine though. I'm beginning to open my eyes to the benefits of 5w30 in those situations.
