Gilbert drivers who are a couple quarts or liters low on oil don't have enough oil to lubricate their engine properly. The extra friction causes drag that reduces fuel economy.
Same goes for dirty oil. It doesn't reduce friction properly. The result is you get to watch those numbers at your Gilbert gas pump rolling higher and higher.
The transmission also needs the proper amount of clean fluid to do its work. When your transmission is in need of service, the transmission drags your fuel economy down.
So, it's important to keep it clean and give yourself a fighting chance by getting a transmission service at Spectrum Car Care Center in Gilbert.
