Re: Anyone use Syntec oil

i have used it since i got my truck and i dont know about the mpg he got but i can tell you that synthetic doesnt have the build up of organic and you can go farther between oil changes and since i got my truck new i like the idea that i hav had that protection since first oil change and they say it makes more horsepower also so thats abou it

Re: Anyone use Syntec oil

a 2mpg gain from switching to synthetic is highly unlikely. your oil would have to have been really dirty to see even half that.

i use mobil one myself because it's frequently on sale at wallyworld. i have not noticed any mileage gains in any of the vehicles i run it in, but it comes out clean everytime and allows me to run long drain intervals.

Re: Anyone use Syntec oil

my truck has 15k on it...would it be ok to switch to syn? and will it void any of my warranty? and i dont just mean engine oil either, im talkin about the diffs too..or is that a bad idea?

Re: Anyone use Syntec oil

I run it in 2/3 of my rides...the Ford marks it territory due to the rear main leaking. :D

Anyway... you can push M1 for a long time. I ran it to 20K in my Z71 (changing filter and adding a qt every 5K) and the motor runs as strong as can be.

DO NOT waste it by changing the M1 at 3-4K mi, it simply lasts far longer than that.

Also if you're going to run oil for a long time...make sure that you use a damn good filter (NOT fram), because even if the oil is still good, it picks up dirt.

I use the cheap ass filters from Pimp Boyz as they are reboxed Purolaters... FYI

synthetic oil won't void your warranty. and as fas at the rear diff, it probably already has synthetic in it. just check the manual to see what it has.

hastings and baldwin are two excellent filters.

What do you recomend for a good oil filter?? now that i just rebuilt my motor im using syn oil, and i used a fram filter! i thought they were good!!??

Whats a good mile amount to change the oil if you do alot of highway driving?

Re: Anyone use Syntec oil

More freeway driving is better for oil, it goes bad when it gets contaminated as moisture and such get into it.

I went to Syn @ 5K on my WRX, runs great w/o any oil loss.

if you make the bottles for mobil one and we all use it, then we're keepin' it in the family! it's a random phrase i made up on the spot that apparently doesn't make much sense without an explanation.

i check mine every week or two and if i see it's getting a little dirty i change it. i usually run 7500 mile drain intervals with mobil one 5w30.
