[PPCC] Oil for Corvairs/gfox reply

[Shell]

Hi Garrie,

I'm not all that wise on diesel engines but a few things I know about them makes me wonder why the difference in longevity. Anyone please chime in if they would like. 
The first things I've noticed is the fuel. Gas seems to be a much better solvent than Diesel fuel and it would seem to degrade the oils much faster and cause faster wear. 
Second is that diesels are built a little stronger as they have higher compression ratios to self ignite the fuel and need to extra strengths to hold together. 
Third when you compress the air fuel mixture don't you have a more uniform burn (cleaner) vs. igniting with a spark plug?

Thoughts???

        Shell,

        It is amazing what a year old set of data provides and yes, you are using great engine lubricant, Delo 400. Between Bob Helt's Corvair recommend procedure for selecting Corvair Engine Oil and Kermit's great search results, we are having fun again on this subject!

        I looked at my last year's five quart engine oil jugs and the ratings changed just in one year?

        That "near the end" click on link was very interesting as it gave all the CI-4/SL or plus oils from the various manufacturers.

        I recently read that manufacurers of over the road tractors give an extra 250,000 mile warranty if synthetic oils are used.

        Regards,

        Garrie Fox

          Very good article. It makes me feel good that we at least use Delo 400 in all of our cars and trucks and have for the last 5 years. Just as critical is the oil filter and changing oil religiously (no surprise).

          Just as interesting in the section where he tries to debunk some of the myths concerning flushing, synthetic oils and adding after market additives.

          Thanks Kermit for digging this out and thanks Paul for forwarding.
