Lets compare.............. These lower hp V-6s aren't that much better are they? Notice they both have a 5 spd auto...Try some research before you post something like that.

I dont know why your comparing V6 cars to a 4 banger. MY Cobalt SS is a 171 horse power 4 cylinder. Now research the 4 cylinder Toyotas and Hondas and repost and get back to me with that.

He was comparing japanese V6's to American V8's. Trying to show thhat GM V8's get almost as good mileage as japanese V6's. But as for your cobalt....

Per the specifications, the Cobalt is right up there with the japanese cars. I still say you need to get yours looked at if you're only pulling in mid 20's on the highway. That intermittant SES light isn't coming on because it wants to. There's something wrong.

I've heard others claim this, I often wonder how hydraulic lifters operate without oil.

They don't. At least not correctly. It will run, but it will have substantially less power.

There was a guy in highschool we used to hang out with who was trying to get some insurance money or a new motor or something to that effect. Anyway, he completely drained his plain old conventional oil with absolutely no addtives in his 1992 Chevy pickup with a TBI 350. Then he purposely drove the hell out that truck for a while fully expecting the motor to grenade any time. He ended up driving that truck with no oil for over a week before it finally tied a rod bearing up.

I suspect it has little to do with the type of additives or type of oil, and more so the bearing clearances and journal runouts from the factory.....and maybe a little luck.

Some of my Coworkers here have the new honda civic Si, Subaru STi, and Toyota Corolla S, Neon SrT 4. Besides the Srt all average 28+ Anmd they beat the hell out of there rides. I just came from lunch I am actually at 22 average. I will definitely make an appt to find out whats the problem with my car. Thats just rediculous now how bad the economy is on a new car.

Got my K&N filter today and installed it. I filled the tank to start it from scratch. My economy was at 21.6 a gallon. I drove to my ladies house 35 miles economy was at 22.0 when I got here. So some improvement lets see how good it does at the end of the tank.
