Have input half bottle of tufoil into my 40 year old vw beetle engine because it uses only 2.5 Liters of 20—50wt engine oil.
Did it run smoother???
Don’t know! Because the original engine make so much noise anyway… hahahaa :o)
But more seriously…
The vw beetle aircool engine temperature used to be 220F and now, only 200F
A 20F degree drop – have to be tufoil, couldn’t be anything else because I didn’t anything else.
