[Responding to a message about better gas mileage with Redline....]
I can attest that Redline resulted in lower oiltemps, even beyond 500 miles
on the oil .. vs. Mobil 1 0W-30.

I've done back to back with Mobil 1 and
Amsoil 0W-30, three times .. each time, Mobil 1 caused an increase of steady
crusing temps, from 215 to 230. Always there when cruising at 70 mph on the
highway, independant of temps outside. Put Amsoil 0W-30 in, and it goes back
down to 215, steady cruising temps.

The 5W-30 synthetic Redline sells is actually about as thin as a 0 weight
oil when cold. Call their tech line and ask about it. They're considering
calling it 0W-30 at this point, but are holding out as they don't feel it's
necessary. When fully warmed up, it is also thicker than a normal 10W-40
oil. This is great for our turbos.

It meets ACEA E2+ specifications, which our warranty requires.

Mobil 1 0W-30 does not. Nor does Amsoil 0W-30.

Valvoline full synthetic also meets this spec .. and they sell a 5W-40 I've
used in the past. The manual states it is an acceptable viscosity.

Redline is really good stuff. At 3000 miles it looks like it just went in-
honey in color. Mobil 1 0W-30 is looking pretty nasty by then. They're
losing my brand loyalty more and more ...
