    MPG tips

    There isn't any wawa's within like a 3 hour drive from me that I know of. I wish there was a chevron station close but it's still 2 hours away.

    Is this Chevy Tahoe or GMC Yukon ?!! HELP for PI Case

    I think it's a Toyota 4runner was my first guess. Looks to narrow to be a Tahoe but it could be the way the pic is.

    MPG tips

    I run toluene 121 octane mixed with a little methane in my 2001 gmc yukon and I get 25mpg. JK'ing i either run shell or ExxonMobil 87 in it and it's almost always in the 14's mpg which I'm happy with since it has 328,000. I've ran Sunoco and a couple local brands in pa and md here an it ran...

    Engine additives, fuel treatment and oil

    I use to just get whatever gas was the cheapest but as my 01 yukon started to get higher mileage on it some of the gases would give me a misfire and a rough idle. So now I stick to Shell gas and my vehicle doesn't have any problems. I 2nd using the techron fuel additive, it's kept my yukon...

    I have the most strange exhaust? Dutch Tahoe

    My 01 yukon has the same exact exhaust too. I've always wondered why it has dual pipes out the muffler for like a foot, then turns back into a single.

    Is any1 using or used any Castrol full syn?

    I have been using castrol edge full synthetic 5w30 high mileage in my 2001 gmc Yukon with 325,000 on it and have never had any issues. I also run a k and n oil filter and have heard a lot of good things about the wix oil filters. I believe Napa's brand oil filter is actually made by wix but i...

    Newbie 2007 Yukon

    I have a 2001 gmc yukon slt with a box in the same place and I believe mine is the cruise control module. Could be something different on yours being newer but I'm pretty sure that's what it is.

    Front electronic shocks

    I have a 2001 yukon slt with autoride. It still has the stock shocks on it but i had to replace the compressor at about 220,000. You can unhook the airline going into each rear shock and pump them up with your home air compressor to see if they have leaks or will hold air. My old compressor i...

    Looking to buy my frist 01-05 Tahoe. What problems should I look for?

    Don't know if you already bought one but I would definitely check the brake lines especially if you live in the Salt belt. The rear main seal, transmission I hear alot of people on here complaining about there's but I've never had a problem with mine. The heat/ac front and rear cause the...

    2 Yukons with bad transmissions

    I must be lucky cause I have 324,000 miles on my 01 yukon 4x4 an my trans. I have never had a problem with it. Bought it in 2009 with about 92,000 on it and as far as I know it's still the stock fluid cause I haven't flushed it or changed it since I've had it. Knocking on wood lol

    Oil and filter recommendations

    I live in PA and have a 01 yukon. I use to run castrol gtx high mileage 5w30 but about 10,000 miles ago I switched to castrol edge 5w30 high mileage full synthetic with a k&n oil filter and i love it. I got 323,000 miles on my vehicle and was kind of worried about switching to full synthetic but...

    2005 Tahoe Daily [Update 06/25/20 - leveled?]

    Looks good and sounds like you got a good deal. I have a 01 yukon slt bought it in 09 with 90,000 and now has 319,000. Haven't had any problems but the usual shit like brake lines, fuel pump and regular maintenance. Are them rear quarters cut out some cause looks like alot more space than usual...

    No codes...but feels like fuel pressure or spark hesitation. Help!

    Could be one of the coil packs, plugs or wires. I have a 01 yukon slt with 319,000 miles and still has the stock tranny but back to your problem i would hook up a obd scanner and see if one of your cylinders are misfiring that would be the easiest and cheapest way in my opinion.
