Miles Per Gallon
#13
x2. my truck got an extra 40 miles per tank when i added almost 10 psi.

This past weekend I have changed to 5W30 over 10W30 castrol edge syntec. Aired up tires to about 36 psi, still 28 mpg.
I was checking under hood & noticed in between the "V" of the exhaust manifold is a crack about 1/16" wide & approx 3-4" long. Will this cause mileage loss? I looked up on ebay a new catalytic & manifold just under $200

Cracked manifold is not good. Air coming through the crack fools the O2 sensor and makes the ECU run the engine rich.
Beware a lot of ebay "converters" don't actually have catalyst in them. They're just hollow shells.

@mk378 That may be my problem. On ebay I was looking at the whole manifold with cat converter on it. I know they have those so called "High flow cats" that are just a pipe. I was also looking online yesterday that permatex makes a super high temp putty for manifolds , I may look into that

Yeah, I'm pretty sure your car has the one-piece cat-exhaust manifold system. I think all 6th gen non-vtec engines do. I tried a lot of different high temp putties when mine was cracked. they would stay on for a week at most, and then they would burn off. The price on that ebay manifold-cat is pretty good, but I couldn't tell if it came with a new gasket or any other hardware. Dorman makes a direct replacement that is carried by a lot of autoparts stores. The part number is 674-439.

So for sure get the manifold fixed.
