Mobil1 Advanced Fuel Economy oil really does work
 

i did a few oil changes with some mobile1 advanced fuel economy on my aveo. well last oil change, i used just plain mobile1. ive noticed a big drop in my mpg.
i was getting around 31-32.5 mpg.
now i was getting 25-27 mpg.
i just changed my oil yesterday back to the advanced fuel economy and im already noticing a big increase in my mpg. when this tank is empty, well find out what ive got.

I don't see anything in the gaslog to support that assertion... unless you changed the oil after only one month starting 12/17... and why would you do that with that few miles? It doesn't make sense to me :confused:

last time the oil was changed was around thanksgiving time.
i drive a lot back and forth from work. i already reached my 3000 mile mark on this last change.

am i alo supposed to report when i change my oil??? :confused:

If you are going to make fe claims re: oil... yes.

that sounds a little overboard IMO.

I run mobile 1 SUV and change the oil every 10K, changing oil every 3k with synthetics is a waste of money and resources.

My thoughts exactly.

I run about 10k on synthetic and a WIX filter too - just have to make sure it's topped off once in awhile.

Americasfuture - I will be anxious to see if the next few tanks come up. Winter temps should still be the same as your last few.

yea, im anxious too. well see when i top my next tank off tonite. this one is half tank old oil and half tank AFE oil, so it wont be an accurate reading. and i gotta keep my foot out of it when habing to go up a hill against the wind.

god i hate oklahoma.....

Same viscosity oil, synth or dino, are within 5% FE one to another. And I'm being generous.
