On Castrol web site they do not show GC to be energy conserving. Syntec 5w30 is though.
Is GC thicker than syntec 5w30 ???

So it isnt posible to go from a 5W-30 syn. starburst to GC 0w-30 and get better gas mileage right?quote:

GC does not have the starburst on it, so it is not listed as an Energy Saving oil.
No, There are some American made Red Label Castrol 0w-30 bottles out there, but they have a starburst on the front. Makes it east to tell the difference between GC and American 0w-30.quote:

OK, got a pic of red label AC with the Starburst. Camera phone pic.quote:

Not all the info but basicly the EC oil has to show a 2-3% mileage improvement over the a non EC baseline oil. then there is an EC-I and EC-II they differ as to improvemnt and vis grade.

Did you note the date code on the bottle?quote:

Like Bruce said. API and ACEA are essentially doing the same thing, but with different reference oils. It is entirely possible to get the API starburst, but not meet ACEA requirements, the starburst would indicate energy conserving and would therefore not meet ACEA standards.quote:

Motor oil viscosity is a very minor factor in fuel economy. Adding 1 PSI to your tires is probably a bigger factor.

And don't forget some places use reformulated gas in the winter which also decreases mileage.quote:

hehe.
Here's an interesting thought- an engine gets better economy in cold weather because it can get more condensed air and provide better compression/combustion. But then that economy is lost because the tires will have lower pressure at lower tempurature. Thicker air also creates more wind drag!!! Oh- and the oil in the tranny, differencials, axles, would all be thicker on a cold day. So where does it all balance out???
RIGHT????
hahahaahahahahahh, so many little factors.
