Does 4.3L V6 get better MPG than 5.3L?
#13
While on the subject of fuel economy, I’ll weigh in with my 2cents. With all the claimed ‘fuel savers’ out there, I found 1 that was cheap & worked. A trip form Tulsa to Dallas, I used to run thru about ¾ of a tank each way. Now it takes a little less than ½ a tank. The only thing different was the Lucas upper cylinder lubricant in 2 tanks of fuel. No fancy chips or mods, just a 32 oz bottle for $10 at the auto store – enough for 2 tanks in each truck and the cobalt. That with regular oil & fluid changes- they are all running further, soother and about 5MPG higher. Everyone has opinions. That’s what happened to my 3 Chevy’s. It’s a mildly hilly drive in spots. I drive with my cruse at 60 to 70 (75 on the turnpike.) Different cars, speeds, terrain and driving styles may have different results. I didn’t do any lab tests LOL.
