Just wanted to let you know about my beater car that gets me good gas mileage, and ask a few questions.
My car gets 41.96 MPG when driven carefully under 80% highway 20% stop and go.
Believe it or not, those numbers were with 2 quarts of lucas stabilizer and 2 quarts of Valvoline High Mileage oil.
The car burns oil at startup, so I suspect valve stem seals, but I dont have the time or money to fix it.
I have recently switched over to Castrol 10w 30 High Mileage oil and it seems to smoke the same or less now.
The air conditioning compressor locked up on me, so I can't use it
I am probably going to pop a new one up there because driving down the highway with my windows open is killing my gas mileage, but with 100 + degree summers, and close to 100% humidity, I can't get around it since I am forced to wear businesss casual.
I feel blessed that this forum does exist.
Any thoughts on my car and getting better gas mileage? FYI it is the 1.8 SOHC in this car.
Tell us a little bit more about your Protege...is it the 5-speed, how many miles?
Also, what part of the world are you in? -- an approximate area is OK. (Sounds uncomfortable without the A/C).
I understand with the air, though -- windows down on the highway is bad aero, but the compressor uses up the fuel -- and business casual isn't very good soaked. Problem is, you'll probably see a decrease in economy if you replace the compressor, since it will probably be used in City driving.
But, there are ways to improve beyond your baseline, even with the A/C...
