Hi folks. I just thought I'd share this for anyone curious or for any thoughts. I have an '02 Taurus with the 3.0 OHV Vulcan. Currently 104k miles. I've ran Valvoline Maxlife 5w20 (the blend version) for almost the entire 7000 miles I've had the car. At cold starts on cool or cold mornings I noticed some ticking for the first minute of idle. I did some Techron, Seafoam and finished the OCI with Rislone with no change in the noise. So I decided to try a thick 0w20 in which case Magnatec seemed like a thicker of that grade. It specs an 8.511 100C viscosity versus the Valvoline Max's 8.9. The cold start noise is gone but after two days of driving with the 0w20, my low oil pressure light flickers occasionally at idle in hot stopped traffic. I wonder if these instances point towards not-so-great internal tolerances, or is the 0w just too thin? I guess I'll look for a 0w or 5w20 with a 100C visc of 8.9 or better. Or maybe I should use a 5w30 like this engine was spec'd for in earlier years? I sure did like the Magnatec. The engine is SO quiet and mileage is already showing a good jump.
