    I recall seeing someone mention that they lost MPG when the went to mobil 1.. I just changed the other week, and noticed that the fist tank went down as well..

    Is this happening to anyone else? Just installed the Afe yesterday so we will see what happens..

    Are we talking about a big loss? or just a few mpg?

    I will be doing my second oil change when I get back to Texas on Tuesday. I am going to Mobil 1 just like I did with my 2.7L engine. Can't say I saw any change in MPG with that one, but we will see...

    Were you driving your usual routes? Did you change your style of driving at all during that tank. Run a few more tanks than compare the #'s. Average gas milage cannot be determined off one tank IMO.

    For my first 5000 miles I averaged 19.3 mpg. Thats city and highway. Mainly back and forth to work.

    I changed to Mobil 1 synthetic today.

    My next 5000 miles should be the same style driving but only a different season. Winter. We will see which way my mileage goes...up or down........

    don't think mine changed at all, but my truck is pretty well broken in. it also might have had syn in it when i bought it.

    Ben, Your not going to get a decrease in MPG switching. All my vehicles have gone up a mpg or 2 when I switched.

    good deal Chris, doesn't really make sense to decrease to me anyway. As long as all other conditions are similar......with winter, I do have more gas consumption with warming up and scraping windows etc. So I will have to check next year during the same season to get a similar comparison I guess.

    same here. being that its getting pretty damn cold now...........i think mpg's will fluctuate a hair,but it'll be relatively the same..............a bit better with synthetic though.

    cold air is denser air, MAF sees more volume going in the engine, ECU says "I can put more fuel in", mileage goes down a tad?

    (question not fact)

    There's no way you're going to see a decrease using a synthetic unless you're using the incorrect weight.

    Possibly, but most likely my guess is that it would be the winter fuel blend.
