"To separate fact from fiction and really find out for ourselves how big this zinc-less oil issue is, we did our own experiment. The test mule was a newly restored 1967 Pontiac GTO 400 V8, four-speed convertible. The plan was simple: fill the freshly rebuilt engine with break-in oil and do our normal startup procedure. Fire the engine and take it to 2200 RPM for 20 minutes, then idle down through the RPM range and make any adjustments needed. We then would put a few break-in miles on the engine to seat the rings under load. Next, we’d drain the break-in oil and fill the crank case with a good multi-grade oil without zinc and replace the filter. Next, we were to drive the car under normal road conditions for 500 miles and pull the engine apart to check for wear. The internal components consisted of tried and tested combinations that we knew worked well. The engine ran flawlessly through 50 to 60 miles. But at about 80 miles into the test, we noticed a slight tick that quickly became a knock, which a stethoscope confirmed was coming from the top of the engine.
The engine still made good power and ran fine but seemed to be getting worse with the knock. We pulled the engine and removed all its parts, carefully inspecting each of them. Overall, the internal parts looked as they should, basically new. There was one big exception: the camshaft and lifters. We saw right away that the cam lobes were visibly flat and worn unevenly. The bottom of the lifter base was also worn excessively for an engine with 80 miles on it. The camshaft and lifter set were manufactured by one of the largest cam companies around and we have used this same cam number at least 50 times with no issues at all. The cam pictured is the actual camshaft from our test car.
The results of this test were so convincing to us that we spent the next six months working with oil and lubrication experts to develop our own engine oil with zinc protection. Some may say that is an extreme reaction, but it’s pretty normal here at Surf City Garage. We have to know for ourselves what’s in the bottle. Today, Vintage Car Motor Oil is all we use in every one of our 100+ cars."
