nope nothing i only lost a little bit that u can hardly notice when i got to the lincon tunnel, was in traffic for like 40mins. i am so happy now, i just replace all belts, complete tune up etc... my car is so smooth i love it but i love to be in the passenger side i dont feel a thing and the best of all it is so drop and still feel good, riding on tein ss. i notice the hugeee difference between honda atf and aftermark fluid. my goal is 3-4 weeks with one full tank driving about 10miles a day n this crazy azz traffic.

 

it seems like a lot of fuel gauges indicate fuel usage is greater at a half a tank of less.
Maybe you loose some to evaporation somehow.... nevermind that was stupid.

 

87 all day every day. Higher octanes will get you a slight, slight increase in mileage, but it doesn't make up for the extra money you spend.

Better ways to improve your mileage: clean your injectors, adjust your valve clearances, use cruise, stop driving like a bat out of hell.

you know what helps a lot???? new sparkplugs. (i speak from experience) I would recommend Bosch Platinum sparkplugs.

 

NGKs, stick with OEM type plugs, stay away from German plugs.
