Lunati DRV02006 10W-30 Driven HR-2 High Zinc Hot Rod Oil for Flat Tappet Camshaft, 1 Quart

Love this oil! I use it in my old 1983 Chevy pickup with a 350. I use it since flat tappet motors benefit from the added zinc that isn't in todays oils like it used to be. I also love it since the truck does little driving and is stored half the year. In my opinion, it's worth the cost. Especially for me, where I only do one oil change per year.

We put this in our rebuilt boat engine, originally a 1990 Mercruiser. The machine shop where the engine was built said this was about the best oil we could run due to its high zinc content to protect the camshaft at high RPM. This oil has awesome storage protection properties so its extra piece of mind while the boat sits for 7 months

Great product, excellent shipping

bought a 1972 chevy truck with 350 v8 rebuilt engine - lifters were noisey - changed the oil with the Gibbs oil and WOWengine runs much quieter - must be the zinc that did the job - I am sold and glad i paid the extra for this oil

Great for zinc requirements

Using this in my 1971 Dodge Dart. Highly recommend for older engines which used to run on lead added gasoline.

Works as described. Good break in oil for a forged Subaru engine.

Used it on the last two oil changes, 6,000 miles, great in my old Y block
