I can't seem to find it from any brands like Mobile1, Castrol,...

What made Honda switch to it? And where to find such grade oil other than dealers?

 

I use Mobil 1 synthetic. You want the Mobil 1 0w-20 for the Acura TL's. It's specifically made for Acura's and Fords that normally use 5w-20. Says so right on the package. I love this stuff. Autozone, some Wal-Marts and Checker's has it.

 

there's alot of info about this in the search button but to sum it up it's your fed govenment asking you to sacrafice a bit of engine protection for better fuel economy(I believe if there's is a differance in fuel consumption it only until the engine wears down because of the lesser friction protection)

 

Its purely for boosting their Fleet MPG stats. Not too noticeable on a per car level, but when you consider all the cars they sell, each little fraction, eventually adds up. This is something all manufacturers keep a close eye on with all the standards set for cars nowadays in regards to fuel efficiency.

 

I noticed a little difference after switched to M1 5w30 synth. The engine feels like it encounters more resistance than when it has the factory 5w20, when trying to spool up, and that feeling of " Honda raw force" is gone.

I ams saying the engine feels more " Nissan" and less " Honda" than it does as a new car. Hope those who drove both brands can understand.:p

 

According to some of the UOAs I've seen, these low viscosity oils like Motorcraft 5w-20 have been generating some excellent wear numbers. The rationale is that the low viscosity reaches the oil lubed areas of the engine quicker than higher viscosity oils after startup, reducing wear significantly. Once up to operating temp, the oil film seems to hold up well under high load areas too.

 

i dont know how thats possible, i use 5w30 (mobil1) and it cranks faster than normal oil

 

Actually I do have to say that my engine seems to take a bit more effort to start after I switched to synthetic. I never once have had to make two attempts at starting it, but it does definitely turn over a few extra times during those cold mornings.

Overall though, I'm happy with the results.

 

What are you waiting on!
Redline 5W-20

the engine it self should crank faster (not start faster) with the synthetic in it due to it not becoming so thick when cold

 

Very True, But the first number in viscosity is what determines start up protection(cold protection) so 5w-20 should be no differant at start-up than 5w-30. but the high RPM and hot weather protection differance is undissputable
