By my calculation, that's 25-26 mpg, which, if mostly city driving, is typical and not bad for this car. I wouldn't call it a lot. It should probably get about 30 mpg highway.theaveng said:It guzzles a LOT of gas, $7000 worth over the ext 50,000 milles.
You could try Lucas, but that's generally only good if the seals have become hard and are indeed the source of the leaks. Even then it's a temporary fix.theaveng said:The old EPA test rated it 27mpg highway (which is my average too). . But I don't want to get into a debate about how $7000 over 50,000 miles is a lot of gas money, and other cars exist that would cut that expense in half. I want to focus on the Avenger: What about that thicker transmission oil? Is that an option?
Yes that is my longterm goal, since I figure the transmission is already shot, with my dealer telling me I need a new trans pump and new torque converter "plus maybe other hidden problems". He said it would cost me $2000 at least. So I've decided to just drive the transmission as long as it holds out. I should be able to get another 50,000 out of it.If you are looking to kill the transmission, then yes - put thicker/wrong fluid in it.
