Good catch Frank!

Oil spec is 5w20 or 10w30, dino or syn. Running Pennzoil Ultra 5w20 and have no idea what the spec is for oil temp, but the sender is also the drain plug so it's reading average sump temps. Oil viscosity is based on 212f, so I'd rather run a shade cooler (thicker) than too hot (thin).

Basically, I wrapped the filter with header wrap and aluminum INSULATION tape, and then used a small soldering blanket which is like header wrap for the pan.

BITOG is a great site.

If your car is designed around a 8.5cst (xW 20) oil at an oil temp of 212f, then at 104f the oil is 30-48 cst, or WAY thicker than even a xW60 at 212f.
Too thick and it kills mpg...
