$300 dollar for an oil change? That's absurd! Just buy a set of ramp for 30 bucks and do it yourself. Even with VERY good quality synthetic, you won't cross $80/change. This "special" ester oil, is NOT even synthetic. I think it's a synthetic blend with ester mixed. You can look at my DIY and get an idea how hard it will be. Good luck
