    High Mileage Engine Oil Use?

    How many of you use high mileage engine oil, recommended beyond 75,000 miles? I know it contains elastomer sweller additive (esters of some type) to lessen oil leaks past hardened and worn rubber seals. Does it make any difference in lessening leakage seen from your dipstick? Less leak spots...

    2024 HD Truck Tire Recommendations? HT / LT

    Planning to switch from AT Class E tires to HT (all season-ish) Class E tires. Anybody experienced out there? Towing a 7,000 lb Travel Trailer with Ram 2500 truck. Been looking at these as a more reasonable deal than Michelin Defenders, which I've read have been having quality and imbalance...

    Gasoline - Top Tier for 2024

    Gang, Top Tier gasoline certification continues to shrink in my region (upper midwest) - by a lot. We've lost Top Tier Certified Gasoline stations Mobil (pulled out of state to save distribution costs), SuperAmerica (sold to Marathon, which elected to sell only their cheapo non-Top Tier...

    EV Buses Ain't Makin' It Either -

    https://www.minnpost.com/environment/2023/12/road-to-zero-emission-buses-proves-challenging-for-minnesota-transit-agencies/ Who knew EV wasn't a one-size-fits-all solution to CO2 reduction everywhere, for all applications? Except those of us in the business. Politicians that don't listen to...

    Chevy Blazer EV off to a great start.

    Ever more software layered on ever more software is always good, no matter what! Just ask the U.S. Navy that cancelled an entire ship building program because it took the 2 YEARS to get the 1st ship even functional. This is what happens when coders are left to do whatever they want to without...

    Ford F-150 Lightning EV Production Slows

    "Ford’s plan to rule the EV market in the U.S., particularly in the pickup sector, has started to unravel. The Wall Street Journal obtained a UAW memo that shows Ford would slow production of its F-150 Lightning, the company’s EV flagship. The memo also said Ford has begun to build more...

    HD Tire Pressure Observations

    Anybody else find their HD truck rides better at full tire pressure without a load? At least for the 2500 (3/4 ton), which has 5 link rear coil suspension instead of leaf springs? This is the only truck I've owned with the rear suspension like this, and the only truck where full load tire...

    1st Travel Trailer for my Ram 2500

    After 27 years of motorhomes, we downsized to a 7,000 pound GTWR Travel Trailer. I bought my Ram 2500 in 2018 for hauling my contractor utility trailer of the same weight class, so this fits right in. Tows well with load stabilizer bars, I run the 6.4 Hemi in tow program, limited to 4th gear...

    Poll: Reliability vs. Comfort

    Let's say you're in the market for a new truck for whatever reason. You don't want an EV, and you're not brand loyal. Let's also say your research leads to trucks that either emphasize reliability or comfort, but not both. Which would you opt for?

    2023 GM Duramax Diesel 3.0L I6 - Test Drive Impression

    Due to all the hubbub going on with Stellantis truck model changes, and issues with Hemi engine design never resolved, I went to see what a GM Duramax Diesel truck was like. I haven't driven a GM truck since I got rid of my oil-pumper 5.3L AFM engine in 2012. I read up what is going on. GM...

    GM doubles down on V8 power for trucks.

    Not only gas ICE, but Duramax Diesel ICE, too. They bought out Isuzu last year and are expanding the engine plant. Like Gale Banks, they know batteries ain't makin' it for a truck. Meanwhile, Euro-Stellantis is sending Beemer-mobiles. Fail. We may all be going back to GM...

    Pre-Lubing Hemi Engines after lack of use

    Today I wanted to test Hemi engine pre-lube functionality without AlphaOBD or other tuning. It was mentioned elsewhere in the Forum. My truck has been sitting unused for weeks. I'd been riding along in other's vehicles instead. This consists of depressing the gas pedal to the floor and...

    MOPAR ATF +4 Spec Sheet?

    Has anybody ever seen a Spec or Data Sheet for MOPAR's ATF +4 automatic transmission oil? I can't find one on the interweb. I'm looking for MOPAR's sheet, not an aftermarket supplier (of course, an aftermarket supplier provides the oil to MOPAR, but I wanted to see the OEM spec requirement)...

    Hemi Exhaust Manifold New Design?

    I decided @ 47,000 miles I'd better get my 2017 Ram 2500 with 6.4 Hemi exhaust manifolds machined before they leak and break bolts. Seems like a 100% fail rate for Forum Members. Today I called up our local expert Tim's Custom Exhaust in Minneapolis - he knows all about it, says they do "4 or...

    Cummins OCI for B10 Fuel

    Anybody with a Cummins 6.7 diesel engine know if their Owner's Manual states to reduce the OCI when using biodiesel fuel? Years back, they used to require OCI's cut in half, when I worked for them. Curious to what they're saying now, since we still have a couple of diesels in our inventory...

    More EPA Diesel Exhaust Regulations?

    This just came out today. I don't get it - I thought EPA OnRoad Tier 4 Final diesel engine exhaust regulations we have now made engines near zero. What gives? Anybody here in the industry that speak to this? Keep out of politics, please...

    Coolant Change Method Survey - Hemi

    I plan to 1st change Hemi engine coolant this spring. With increasing shop rates and suspect labor quality, many of us are going back to doing more maintenance ourselves. I'm curious how you're doing things these days, with better quality materials available than decades ago - are you going to...

    Parts Washer Recommendations?

    I'm tired of wiping down truck parts with various solvents prior to re-installing. My sons like to use spray brake cleaner onto oil absorbent. For old guys like me, that's pretty messy for periodic routine maintenance (oil pans, gearcase covers, fasteners, etc.). 40-50 years ago, school shop...

    Air Suspension Kit for 2500 - Recommendations

    Members - not sure where to park this post. I put it here in Heavy Duty since I think it needs a unique suspension. My truck is Gen IV, of course, 2017 Ram 2500 Laramie Crew Cab 4x4 with 6-1/2 foot bed. This model year added all coil spring suspension. It rides pretty good - until the Feds...
