Re: 0-20W Oil
I have two HCH's. One personal and one company car. I have always, since the first oil change, used Mobil1 0w20 and Mobil1 M110 filter in my personal HCH. I have close to 73,000 mile on her and usually get 48 mpg. The company HCH only has 15,000 miles on it and has always been serviced at the dealer, including oil changes. I'm luck if I get 42 mpg on that one. I drive them both the same, but for some reason my personal HCH seems to run a lot smoother. Couldn't say for sure if its because of the synthetic oil or not, but I'm not complaining.
