Like title says, finally changed to 5w20 from 10w30 as recommended by my mechanic, gas prices are KILLING me, I hope this helps with some MPG. I've been semi "hypermiling", best so far was 30.4mpg with a 10" sub and amps in the trunk(downgraded from a previous heavy ass system). I changed air filter, aired tires up to max rating. This is an automatic, any other suggestions for MPG? Plugs are decently new, but wires might be old? that effect MPG?
The only shitty thing was 5w20 cost 26.99, 10w30 was only 19.99 why the difference?
