What oil should I use in my ( Buick Grand National / Turbo T / Regal T-Type / Turbo Buick / Turbo Regal )?
THE ANSWER IS:
Our older 1980s Buick Regal vehicle engines (with flat tappet cams) NEED oil that contains lots of ZDDP (which is a zinc concentrate).
This can be most regular type oils PLUS an additive like ZDDP (many manufacturers make something like this) put into the crankcase.
Or it can be a specialty type oil that already contains a zinc mixture in it.
Some bottles of oil state the words “high zinc” on them, which is what you want.
Some oils say they have a “zinc additive” in them, but use caution, as that doesn’t necessarily mean it has A LOT of zinc in them!

HERE’S WHAT YOUR FELLOW TURBO REGAL OWNERS ARE USING:
(for stock to semi-modded G-body Regals)
Valvoline VR1 10w30 or 20w50
Shell Rotella t4 15w-40
Brad Penn
Amsoil Zrod
Schaeffer’s supreme 7000 10w30 high zinc
Lucas oil (1200 ppm of zinc)
Mobil 1 Full synthetic oil 10w30 or 10w40 or 15W-50
(just make sure the oil doesn’t get to 250 degrees which is where non synthetic breaks down)
.
Those motors that have a roller cam in them don’t need to worry about the zinc component at all.

If you had your 3.8 liter turbocharged engine built specifically by a Buick engine expert, then ASK THEM what they recommend to use!
Then stick with that for the life of your Buick V6 motor!

AND before you ask, YES, you should be using a quality oil filter as well:
Wix or NAPA Gold (made by Wix) filter, is a great filter to use in the Buick V6 3.8 Liter turbo engine.
