well with the price of fuel in the US higher than we are used to paying for, i've been looking for ways to get better fuel mileage.
in my '05 subaru legacy gt i changed out the oil with Royal Purple. i gained on average 3-4 mpg more. in the '02 accord i did the same oil change. not real sure what the fuel mileage increase has been, but its quite noticeable. also with this oil, much smoother running conditions and in the accord very noticeable passing power increase.
not sure if its such a good idea to put synthetic into my '87 accord's engine. its getting close to having 150000 miles on the clock. but i have had the head rebuilt and the rings seem to be in nice condition. what i'm worried about with this older engine is that the synthetic's cleaning abilities compared to conventional oil may loosen up deposits and it will start smoking oil from the exhaust. any suggestions for my 3gee? or should i stick with conventional? dunno if it could also free up things that would create problems in the other parts of the oiling system.
