I use Mobil One In my truck and car. When I used it in my car (has about
60k miles) I got a lot of crud out of it. Cleaned it up real good. I later
read that if you switch to synthetic, you should change the oil after 1,000
miles the first time you use it. I would have to agree with all the junk it
loosened up. Otherwise I am very satisfied with Mobil One, plus you can
get it pretty cheap (well as cheap as it gets) at Wal-Mart - about $19 for 5
quarts. Since it is expensive, I will probably alternate Synthetic with
non-synthetic, the reps at Mobil said it would be fine to do so.
I'm interested in Royal Purple, as I've read articles about it in two different
mags, Hot Rod and I think Road & Track. One thing they said was that it was the
only synthetic oil that they ever experienced a dyno noticable increase in
horsepower, just by switching motor oil.
Red Line Racing makes a synthetic that is as good or better than Royal
Purple from what I've seen. Red Line is not normally considered for street
use by most people because it is cost prohibitive compared to Mobil 1. If I
owned a race vehicle, it would get it though, but for now my truck gets
nothing but Mobil 1.
I've used Mobil 1 in my cars and trucks for several years and recommend it
highly. I also use Mobil 1 for motorcycles in my touring bike. The Mobil 1
for bikes is a bit harder to find around here though and I'm considering
trying Amsoil. I've heard good things about it, any opinions?
