woooo hoooo i'm back to 15.69 mpg . had to drive 2 hours yesterday at 5:30 am to go test for LPG cert. then drive 2 hours back to work . just finished running that tank out and checked the mileage :-)

 

So... Macgyver,
What you driving anyways?

 

EXCELLENT!!!

BTW, good luck w/ your cert results!

Take care,
-Chris

 

Good. I think I'm up to 13 or so now...after 3 months of listening to my ping, I've finally eliminated it. yeaaaah. A whole new monster now. I'm using OD again too.

 

inski,

How did you eliminate the ping? (are you talking detonation?) I have a nagging ping as well, and the truck is such a dog, especially in overdrive and part throttle situations. And my mpg sucks too.

thanks alot,
scott

 

wed I was able to check timing that was acceptable at 8 btdc-I'll bump it once I have time again.

Made sure 7&8 wires weren't running parrallel at any point in their paths. Seperated with zip ties where necessary.

Did a Wynn's 3 part Fuel System Clean... to rid cumbustion chamber and intake of carbon build up.

To be honost I think it was the 7+8 wires all along!

I'll let yoy know how far I can go w/ timing. Now that ping is gone I bet at least 12 maybe even 14. It feels that good.

 

Thanks,

I'll try seperating those wires today. I'll let you know what happens...

won't know if i passed or not for a week and a half . i drive a 1990 F150 XLT lariat 5.0 L w/ AOD and 3.55's with 235/75r15 cooper lifeliner II's (28 inches tall )

 

..I just picked up a 1990 F350 ( with the 5.8 litre )...I noticed that you had gotten your MPG to an almost acceptable level....

What have you done that was the most effective, yet not too $$$

Just curious, cuase I'm pulling about 10 right now if I'm lucky....

Truck runs great, but it's a pig.

 

colorado,
remember, an f350 is a seriously heavy truck, so its gonna be tough getting good gas mileage on a heavy truck like that with a 351.

 

I realize that it's going to be bad...but I'm hoping to get away from " horrible "

 

The usual tune-up stuff. Plugs, wires, rotor button, cap, fuel filter, K&N air filter. Check timing and adjust as needed, check alignment and air pressures. 10 mpg in a 350 aint bad.

is your rig 4wd?

 

as inski said . but i also just got done reading the ecm and replacing about $600 worth of sensors and doing a tune up /oil change etc.. it still wasn't back to that mpg (was closer to 13.5 ) til this last tank . when it was really bad before i did all the work i was down to 11.5 .

 

Yep...and did I mention crew cab with slightly oversize tires...

Do the K&N's make a big diff?

and how about retarding the timing a bit?..I've heard that if I get it BTDC ( a couple of degrees ) it can help as well.
