High Performance Engine Oil
 

OK Cost is not a huge issue (although no more than 15 a quart would be nice)
These will all be in 5w-20/5w-30 since i hear those two are relatively interchangeable
I am looking for the best oil out there but I still want it to last 5000 miles or so.

1. Mobil 1
2. Amsoil XL
3. Amsoil race
4. Royal Purple
5. Royal Purple XPR Race
6. Castrol Edge
7. Redline
8. Eneos

A 2008 Accord has an oil-life monitor, and ANY ONE of those oils should out-last the monitor. In other words, you should let the monitor go all the way down to zero. That should be easily beyond 5k miles.

ok since tat is true, which oil is going to be the best lubricant and the best as far as heat transfer
