You don't have to drain it all out either, if it has sentimental value L.O.L. Man thats good.R.O.F.L.
This truck was built into a monster truck it stands 10 feet 6 inches. 72 inches to the bumper.
The engine has only been run for about 30 minutes every two years just to keep it from sticking. Since I don't use it any more I should attempt to sell it. The oil that I put in it was 10W40 Valvoline The engine has 18,000 actual miles truck has been driven about 200 miles since 1983. I was going to change the oil on it this summer but didn't get it done,maybe next year.
