*Background info on my current vehicle/driving habits... 2016 Honda Accord Sport i4, bought it brand new with 6 miles on the odo. I change the oil and filter every 10k miles, just hit 70k and just changed it again for the 7th time. I have a 130 mile round trip commute to work, mostly interstate and hardly ever stop and go.
I used to always chuckle when I would hear someone say that their car ran better on one brand of oil vs another, or was quieter, or more efficient etc... Well I may have just experienced this for myself. I know my car pretty well, and its fuel mileage has always been pretty consistent, averaging 33-35 mpg per tank. Out of the 7 oil changes I've done on this car, only 3 of them weren't with Mobil one AFE. Changes 1-3 were with AFE, change #4 was with Valvoline synthetic, changes 5 & 6 were with Pennzoil Platinum and #7 I went back to AFE...all 0w-20. Thru those 2 OCI's with PP (20k miles worth) I noticed a decrease in my fuel mileage, dropping to 30mpg average per tank with a few tanks a couple of ticks lower. Doesn't sound like a lot, but I really noticed it on the total miles I was able to get out of a tank. I'm kinda OCD and like to log all my fill ups so I can track these things for whatever reason. I chalked it up to the car getting older, changes in the weather and I also got a new set of tires and changed the CVT fluid in that time period. The oil never crossed my mind. So I was coming up on 70k miles and it was time for another oil change so I hit up the local wally world and all they had in stock was the AFE so I went with that. And I [censored] you not, I noticed an immediate increase in my fuel mileage after the first full tank of gas. 1000 miles in and my average is back up to 34-35mpg per tank. Didn't change anything else but the oil. So I guess I'm sticking with the AFE.
