More truck issues. Oil question.

I ran 20w-50 in my worn out oil sucker. Come to find the oil pressure sending unit was leaking only when running. Replaced it and that slowed up some major oil consumption. The first number is the weight 10w40 same weight as 10w30.

I had and old 53 chevy tow truck. That thing smoked bad with the original motor. I gave this stuff a try.

I could not believe how fast it stopped smoking. A 1 hr ride and it never smoked again. Using that much oil that thing must be a crop duster. If its not smoking bad check the sending unit

There the old truck is in the back ground. 25 yrs later I was still driving it.
