Just came from my auto parts store, and noticed they had Mobil-1 100% synthethic in 0W-20. The
bottle said it was designed specifically to run in Ford and Honda vehicles that use 5W-20.

I'm from the old school that thicker is better. :killer:

Anybody ever use a 0W-20 weight oil in their Acura???

(pretty soon, we'll be changing oil with cans of WD-40)

thicker is better if you live in hot climates that need stronger viscous oil so it doesn't break down as fast... if you live in colder climates then you would want lighter oil because on a cold morning startup, the lighter oil can be picked up from the sump faster... and since it isn't already hot outside of a hot engine, having a lighter oil that is less viscous is okay..

You will be fine if you use that type of oil. I have been using MOBIL1 0-30 and have had no problems. There are several posts on this subject. Just do a search.

No. Any modern API SM oil have tough standards against thinning out a high temperatures. Look at the volatility, VI, and HT/HS to determine the amount of shearing that may occur at high temperatures. Any conventional 5w-20 is more than sufficient for daily use with occassional hard driving when changed at reasonable intervals. The thicker is better myth is ancient history. For better protection in high-stress applications (such as racing or auto-x), try Redline 5w-20 or Amsoil XL 5w-20.

BTW, Amsoil XL 5w-20>M1 0w-/5w-20, even though Amsoil is a GrpIII. It is the final formulation that matters.

I'm using 10w-30 Motorcraft Synthetic Blend. The 0-20, 5-20 oils, etc. are only being used to increase fuel economy!!

Lot of discussion on this in the RSX forums at clubrsx.com. I used to be a die-hard Mobil 1 user, but the MOtorcraft is very, very close to Mobil 1 in "performance" for a lot less money.
