i just purchased a 1950 Chevrolet Styleline Deluxe Coupe. The engine is 3 speed manual transmission with a 216 six inline with 47K original miles. The car has only had 2 previous owners and i would like to do an oil change and filter. The filter i was able to find it online and im going to use the FRAM C4. But i dont know what type of oil to use and viscosity. I was reading about someing called ZINC that it is recommended to use on this type car. I NEED HELP PLEASE reply.

According to Gene Schneider a long long time Chevy fan and parts man Zinc is not needed with these engines, there was no zinc in the oils used originally. 10/30 is
what I used in my 52 with 216. If the previous owners were using non detergent straight weight 20 or 30 wt then I would suggest you change oil and filter again in about 500 miles. Then run the 10/30 about 3,000 miles IF you drive it frequently and warm it up to operating temperature (not to be mistaken for coolant temperature) I used Castrol.

I'm no expert but every engine builder I've ever talked to in the last 20 years has said that a zinc additive is needed in all flat tappet engines, i.e. just about any pre-80 (rough guess) stock engine.
There are several zinc additives available at most auto parts store, just add it to your oil during oil change. 10/30 is probably the most used weight oil in those motors but you might contact the previous owner to see what he used in the car.

Be sure to check your transmission and rear end GEAR OIL level. Don't forget your brake fluid level too. bobt

There was NO zinc in the oil in 1950 and these engines never wore off camshaft lobes.
If you think you need zinc there is more than enough in todays 10W-30 oils.
The valve spring pessures are very low in a 216 engine so the camshaft to lifter pressure is very low.
Too much zinc is also not good.
10W-30 oil is just fine and I would recommend droping the oil pan and cleaning the oil pump screen..

Something else to think about...It probably has a canister filter. The engines are "Bypass" engines, which means only about 15% of the oil will pass thru the filter. I rebuilt my 235 engine before I found out I could have made it a "full" filtered engine, with a spin-on filter. I removed my canister filter, and change my oil about every 2000- 2500 miles. I've read several post on diffetent threads of people who have done the same thing. Castrol 5w-30 is what I use in mine...I have another 235 I've rebuilt with the appropriate changes for full oil filtering in my garage now, hopefully will be starting on a run stand in a couple of weeks. Nice learning project!!

About 75 percent of 1950 Cevrolet engines did not have an oil filter and lasted just as long as the ones with a filter.

all the oil will pass throug the filter but will just take longer....just fine unless you are driving through a dust storm.
