Well I wouldn't have believed it if I hadn't experienced it myself. I have been reading on this forum about the SE syn3 oil and how many of you have already dumped it so I thought I would too. Man the engine is running quieter with the Mobil 1 20/50 synthetic than before. It always had that sewing machine sound while running down the highway, but not now. Went with the Mobil 1 75w90 syn gear oil and it seems to shift smoother than with the bel-ray I had in it. I went with Valvoline 10w40 regular in the chaincase and it is quieter too. I learn so many new things here on this forum, just shows to go ya, ya can teach an ole dog new tricks. Thanks fellows.

 

I agree, for the money Mobile one is the way to go.
