Guest

Recommended Posts

The prevous owner of my 24 special six, ran synthetic oil in it. It leaks around the drain plug, filter, and possibly the main seal. What wieght of oil do you recommend, and how about the gaskets for the side cover, pan etc thank you

The original spec for for a "light oil" in cold weather and a "medium oil" in summer or in warm climates. I use a 30 weight non-detergent oil, as that closest meets what I would consider the definition of a "medium oil" of that time.

Here's my view on oil (I used to work for Shell)

Synthetic oil contains little aromatics. The aromatics in mineral oil (non-synthetic) leach into rubber seals and make them swell and as the car is used, it keeps things sealed. However, when you put synthetic in the engine, the aromatics leave the rubber and go into the oil... so the rubber returns to the old natural size. Since it wore when swolen, then this can cause leaks.

Most early cars DO NOT have any rubber seals, but do have crud built up. Which DETERGENT oils (most modern oils of all types) can clean off (and it is cleaning the inside of the engine too). If your engine is clean, then a detergent oil is good! Modern Multigrade oil (mineral or synthetic) maintains its viscosity over the range of temperatures it is designed for and in my opinion, is good for all cars, old or new (after all it is designed not to get thin in those hot high shear places and thereby retain it's lubricity, but still be thin enough for the high wear cold starts). Synthetic is expensive, and that would be the only reason not to use it.

Now I show my Bias: At Shell, their Rotella T oil (a mineral oil) was considered the best FOR ALL APPLICATIONS (forget that it is for deisels) and is used in most 18 wheelers in the US, some of these engines are 'million milers'. If I could get it in Europe, that is what I would be using now. They also suggested using it in gear boxes..but I never tried that.
