can I switch oil from synthetic to penzoil?
Just bought a relatively new DLE 111 and after break-in, the owner was running redline racing oil @ 50:1. I have been checking to find some in my area and so far, no luck. I can only get it through mail order. I have always used penzoil air-cooled @ 40:1 after break-in on all of my gas engines, but looking at how clean this DLE is after running redline, I think I may have been missing the boat on the synthetic oil.
Not gonna start an oil war here, that has already been done way too much, my only question is: while I wait for the redline to arrive, can I run a few tanks of penzoil air-cooled through it and then back to redline without any harmful effects?
Thanks to all of the experienced guys out there who help the ones of us that don't have as much knowledge about gas engines.
