ago when our engine oil got very dirty, we would drain out the dirty
oil, then add two quarts of kerosene and 2 quarts of clean oil and run
the engine for 15 minutes. Then drain out the dirty mixture and then
add new fresh oil. The oil would then remain clean for the longest
time. I have one hydraulic valve that must be hanging up and want to
try this to see if I can free it up. The tappet is very noisey when
the engine is cold but then quiets when it warms up. The engine is a
V6 Buick Century. Anyone have recommendations or agree with this old
practice???

good chance that will ruin the engine...

change oil, add slick 50 its a super lubricant, and may help.

Don't waste your money on snake oil.
oil additives are worlds better than years ago, and engines dont get
as dirty inside, unless you go way too long between oil changes.

but no oil cleaner or additive will fix a worn out part like a worn
out cam lobe......

best wishes
If the lifter is sticky you can buy Rislone or Marvel Mystery oil, or
you can use kerosene.
If the cam lobe is worn it won't fix it, but usually a worn lobe does
NOT quiet down when it warms up.

What makes Slick 50 'snake oil' and Marvel Mystery Oil and Rislone not? Not
a flame. I just want to know.
TIA,

The makers of Slick 50 were actually sued by DuPont because of their use
of PTFE ("Teflon") because of concerns of engine damage and DuPont's
assertion that it was impossible for PTFE to behave the way that Slick
50 claimed inside an engine.
