GC is just a little thicker than Mobil 1 5w-30. The question is, what is the mpg difference between GC and 5w-20, not GC and 5w-30.


i thought he was comparing mpg between M1 0w-30 and GC, not GC and 5w-20?

He says he uses M1 0W-30 in the winter but 2 different people in the first several posts mentioned that they thought he would be better off running a 20wt oil such as 5W-20 and would get better mpg. 427Z06 said he could tell a difference in a Honda V6 he has and TooSlick agreed there might be a difference. Steelers did mention that he thought GC made his RSX more sluggish than 5W-20 or M1 5W-30 so I guess both oils have been mentioned. Sounds like he's going to try a few different oils so it will be interesting to see what happens.
 
427Z06,
What year is your Accord - '02? The best I have ever registered for an entire tank was 31.7 (488.4 miles & 15.389 gallons), & this was with my wife driving a large portion during our trip & sporadic use of the A/C. Was your result over an entire tank? Of course, I've never been able to set the cruise for 65 mph for that long.
