So would be it stupid to convert to propane? Gas is 3.99 for 87 here. Propane can be had at mid 2.xx a gallon.
11mpg no matter what. Long freeway trip, all in town, all downhill at 50mph... it gets 11. They have a 9th injector and when the ecm senses low fuel usage it will kick on and spray gas down the side of the road.
My 2003 is around 20 at idle with 5W30 @ 187K with 180* TStat. I'll double check when I get back to Nor Cal.What should hot idle oil pressure be on these? I get a good 40 when running and driving, but under 15 at idle. Running 10w30. 35k miles.
should I upgrade the oil pump, or just switch to thicker oil?
Its a 2006.
thank you
Thats what my 02 8.1 XL does with 255k on the clock. I run 5w30 or 10w40 depending on what's on the shelf at work.
Update from when I opened the thread.I just picked up a 2002 Silverado 2500HD with the 8.1/Allison. 2WD. Goal is towing duties almost exclusively (32ft enclosed goose, 10k loaded).
I did not want a diesel nor a payment and this fit the bill.
It's got 130,000 miles. Engine runs smooth, plenty of power, the trans shifts super crisp and it doesn't make any weird noises. Got 14mpg driving it empty with cruise set on 70 for 320 miles, then 11.6 towing my empty car hauler in the TN mountains. So far I'm happy.
Needs a bit of interior work but I'm really wondering about the maintenance of the engine/trans combo. Water pump and hoses changed at 120,000. Tires in good shape and the battery looks recent. That's all I know.
What does irate say about stuff like valley gasket and the other scary things I read on various online forums?
Any ticking time bombs I need to address ASAP?
When do I need to be changing the Allison spin-on filter and the one in the pan ?
Front IFS pops/cracks a little when turning, I'm assuming it needs all bushings/ball-joints gone through ?
Thanks !
Cliffnotes : bought a 8.1 big block, happily putting gas in it but would like to keep doing so for a while, what to do to ensure it lasts ?
Obligatory driveway pic :
The novelty wore off but the 8.1 doesn't impress me much anymore. Does the job but that's it. I guess it's impossible to replace a diesel with a gas engine.
If it was an issue with the master cylinder both front calipers would drag.Bringing this back up to pick the brains of the forum members...
2002 Silverado 2500HD with a 8.1
2 weeks ago I had to do an emergency stop on the hwy to avoid an idiot merging last mine. Full on panic stop, ABS engage etc... Barely missed him.
When I started moving again, the front axle was shaking like a mofo around 50mph for some reason. It never did so before.
I was 2 miles away from home to I pushed on and when I made it in the driveway I realized the right front brakes were locking up. Thick white smoke, heavy brake smell etc...
I let it cool overnight and the next day I took it for a drive. Came back home after 5 miles, same thing happening again.
On a whim, and since they needed pads and rotors anyway, I shotgun new calipers, pads, rotors and hoses in the front. Same results.
I did plenty of testing so here is what happens : When I press the brakes, the right front caliper locks up. Leave it alone for 45mn/1h and it slowly releases. Press the brakes again and the same thing starts over.
I did unbolt the master-cylinder from the booster, same problem.
The weird thing is, if I put a big screwdriver between the pads and rotor, I can pry the caliper open and everything is fine until I press the brakes again. So they're dragging, preventing me from spinning the tire by hand, but not clamping hard enough that I cannot push the pistons back in.
Maybe it's an issue with the pressure relief in the master (???), so I'm going to swap a new master tomorrow, but realistically, I'm out of ideas.
One thing to note, from time to time, I have the ABS light that comes on and off, due to a bad sensor (maybe ?), but I don't think it's ABS related because of the fact that the same problem happens every time I press the pedal. Same thing when the engine is off, ignition off, or on.
Thoughts ?
Thank you

Already replaced...
I was hoping it wasn't that. How much of a pain is it to fix it ?ABS. One of the valves is stuck and won't fully release. Go down a gravel road and see if you can get it to pop free by activating it a bunch.
I can't remember the issue, but I removed the abs fuse for a short amount of time on a '03 ½ ton. That fixed whatever the issue was.I was hoping it wasn't that. How much of a pain is it to fix it ?
I just bought an Autel MP808BT.What is a good scan tool ?
Reading this has kinda made me want to find a low mileage reg cab 2500hd with the 8.1 and 6 speed for a dd
I just bought an Autel MP808BT.
Should do the trick and it was somewhat fairly priced. I chose it over the MP808K for the wireless connection and the Key Programming ability.
Have to look into that.

I feel the same way. I want a manual behind a big block. Kinda want the zf6 never been a fan of the nv4500.An 8.1L allison and ZF6 arent remotely comparable. Fuck autos behind these engines. I've settled for a NV4500 as the ZF6 are too much $, due to duramax prices and GMs retardation of no manuals early on.
