    Bad mpg?

    The part you missed is that in this scenario neither engine is operating at WOT and minimum manifold vacuum. The only difference between the two at the same AF ratio and RPM is the manifold vacuum and mean cylinder pressure.

    Diesel Question

    Yes, and I'm all for unleashing the diesel beasts. Modern electronic diesels with variable turbos are pretty amazing, but nobody's stock Duramax will win a drag race with a 6.0 gas motor. It will get twice the fuel mileage trying, though.

    Diesel Question

    I have older diesels, '94 Chevy 6.5 turbo. They're pigs at highway speed, but get 17mpg compared to 11 in my gas trucks. If you need to accelerate to pass on the interstate, diesels are not for you. They're great pulling a load or for mileage at steady state, but passing is just not their...

    Outside tire wear

    Looking at the alignment sheet, it appears you were already toed out beyond spec...should feel better driving now, but I don't expect the tire wear to improve. The caster and camber are already where I thought I'd put them, probably exactly for the same reasons too. <shrug> It yam what it yam...

    Outside tire wear

    All these big turds have a lot of scrub at max steer, especially the 4x4. Is yours all wheel drive? Toe by itself can help a little, as it reduces scrub at max steer. The trade-off is a muddy feeling in the steering wheel, and eventually tire wear across the tread or even the other edge.

    Is It Worth Replacing High-Mileage Injectors?

    Simple answer is yes, new injectors. I use for my example my '97 Moto Guzzi 1100 Sport. It had about 22k miles when I bought it. I tuned it up using an aftermarket ECU so I have full access to fuel and timing. I took a 10k mile trip, micro-tuning it all the way- having started with a map that...

    Outside tire wear

    I'm laughing at myself this morning re-reading, because yours *is* a Cadillac. Next question is how wide are the new shoes you're considering?

    Outside tire wear

    Turning forces. Here in S. Florida, the RH front always looks like that- the constant U-turns on the boulevards do it. That it's equal on both sides, I'm supporting the theory that it's simply cornering loads. You can have the alignment shop add some caster to help with that- I don't know the...

    Best Magnetic Ride Replacement for Motion Sickness Prone Family

    Sailor's trick; Cinnamon. Keep RedHots or other cinnamon candy handy. Doesn't need an hour beforehand to work, either.

    Ran low on oil

    Ooo, sad face. I haven't finished coffee yet so my spidey sense isn't under control yet. The only times (2) I've seen sudden rear main seal 'explosions'- that is, going from not concerning to flood- is when a piston got holed and overpressurizes the crankcase. Pull your plugs, maybe. With oil...

    Escalade pulls to the left - Replaced almost everything!

    Here in South Florida I'd use that, neutral settings. I see the 2500 has more, presumably because they expect it to tow more and more often. I haven't had my '04 2500XL on a rack, so I can't say where it is. Too bad, I like the way it drives everywhere.

    Escalade pulls to the left - Replaced almost everything!

    ok, that changes everything; if the vehicle was delivered in a right-drive country, the alignment specs make sense. Driving left, makes no sense. Which side is your steering wheel on? If on the 'American' side, the alignment looks like it would drag you into the ditch. Ask your alignment guy if...

    Escalade pulls to the left - Replaced almost everything!

    You can't do it safely. The closest you can get is to remove the wheels, pry the pads away from the rotor (both pads) and go around the block without applying the brakes... unless you're in the country, not likely.

    RV Towing

    The science goes very deep, desperately so. Adding weight directly over the axles changes moment to the better because it's a lower percentage of total weight. Here's the trick, though; if you'd added the batteries all the way at the back of the trailer, thinking to lighten the tongue and be...

    Escalade pulls to the left - Replaced almost everything!

    1. Yes, a rear wheel dragging can cause a pull, especially if the rotor heats up from a sticking caliper. 2. Camber creates a pull, as it turns the tire effectively into a cone, pulling towards the small end. Typically vehicles have camber set to pull left to account for road crown. Yours seems...

    RV Towing

    I worked in the RV industry for a few years, installing hitches and mostly chassis work. The two most common issues with towing were both tongue weight lol But seriously, there is never a downside to using a weight distributing hitch, and they're laying in every Facebook marketplace garage for...

    Front end Rebuild

    I've always been surprised at the quality of parts from Detroit Axle. Their warranties are usually way better than others'. https://www.detroitaxle.com/parts/2002-chevrolet-suburban-1500

    4wd Issues PLEASE HELP

    I wish I was more knowledgeable about the specifics- I have 2 '94s and a '95- but the general diagnostic I'd do would be this; 1. Identify the location of the problem. With the front axle up, engage 4x4, either high or low, and try to spin the front wheels. If they spin without turning the...

    2004 seat height gear repair?

    Fam let the interior stay wet before I got it. Rusted the driver seat rear height screw and stripped the gearbox. I see '07-up gears, but found nothing for mine. Any leads?

    Performance shops in Indian River/St Lucie county Florida

    Unfortunately, the performance herd is thinning. I don't know of any 'regular' hot rod shops that do modern stuff, save the one super high-end shop in the back of the Rio commerce park- they don't advertise and their name is not on google maps. Marty at The Auto Clinic is probably the guy to...

    First post, wiring?

    Ok so my inherent laziness wins again. INFO fuse was open, but separated near a leg like a vibration failure, hard to see. All is well now. Hatari!
