Re: 0W30 fully synth should be ok for my car
[QUOTE=Smaky;2277124]I've given the reason previously in this thread, and we've also moved away from Fully synth in the aero industry too, the oils just cost too much and damage the engine QUOTE]
So it sounds like an expense factor to me.
Synthetic oils can't damage the engine, they lubricate just the same, but don't break down as quickly.
To suggest that the top manufactures are using anything but the best is frankly ridiculous.
