aside from a fully synthetic try adding X1R engine additive or treatment. It makes your engine performs more than you expect. Imagine how a space shuttle done its possibilities... It aids saving fuel and make the engine performs lightly / less friction / better response and keeping it cool. Try it, compatibel to all types of engine (the green box)
