why would you not use synthetic oil? most leading oils are synthetic. Idemitsu is and if I'm not mistaken so is royal purple and I know those work well.

supposedly synthetic doesnt burn as well when injected into the combustion chamber

When I use synthetic oil my car does burn less oil. Does anyone here mix gasoline or use an additive like protek r?

I do not use an engine additive because I have heard so many mixed things on what to use and what not to use. Opinions are great.
