Also stay with mineral based oil on these vintage cars instead of synthetic. While there is nothing wrong with using synthetic, you might see some leaks, due to the difference in the molecular makeup of the oil, the particles in synthetic are smaller than mineral based oils, so they can find any small leak spot that exists, that wouldn't normally leak with the heavier, mineral based oils. </div></div>
Sage advice above, The syn. will also strip the petroleum from the gaskets and seals causing leaks that have soaked up the petrol. oil over time.
Interesting about the use of Rottela in a spark engine as the oil is formulated for a compression engine. </div></div>
The above is true which is unfortunate as the synthetics, such as Amsoil, are much bette
er lubricants and will give better performance, mileage, and engine life. But they will make an older engine leak.
