    Lubegard in a GM transfer case?

    I have a 2017 Chevrolet 3500HD with an electronic shift, chain driven transfer case. I was thinking about adding a couple ounces of Lubegard Platinum to my transfer case on the next fluid change. The transfer case calls for Dexron VI. Is there any reason to not add Lubegard Platinum to the...

    Duramax- Dexcool Change Interval

    How often should I be changing the antifreeze in a Duramax with high engine hours. It does a lot of low speed heavy towing on dirt/gravel roads and idling. The truck in question is a 2016 LML with a little over 55k miles and about 4,000 engine hours. The manual lists 5 years/150k miles in both...

    Post your latest parts purchase

    I ordered a 100% New Duralast Gold CV axle for a 2016 3500 HD Duramax from Autozone online and had it shipped to home. I used an online coupon for 15% off of $75 or more, plus cashed in a $20 reward. Had it at my door for $95.32. It arrived damaged so I called my local Autozone and they didn't...

    GM parts delays - 19 days and counting.

    The Dealer has had my 2017 Chevrolet 3500HD since the 6th. The truck was put into service in 11/2017 and now has 18,000 miles. It is still under the 3/36 bumper to bumper warranty and has 5/100 power train warranty. They're replacing a headlamp on the passenger side that had apparently shorted...

    LML Duramax charging at 15.3 volts

    My dads 2016 LML has been turning over a little on the slow side for a while, but this morning it wouldn't turn over at all. I jumped it with another vehicle and checked the battery voltage with it running after the jump vehicle was disconnected. It was reading in the mid to upper 14's on the...

    Saw these at Walmart today. They say "for high mileage vehicles" like the old Maxlife jugs used to. <a href="" target="_blank">New Maxlife Jugs 9/11/19</a>

    2017 L5P Duramax Fuel Filter (TP1015)

    12,852 miles 522.4 engine hours DIC fuel filter life was ran down to 0%. The L5P fuel filter is much easier to change than LML and prior Duramax fuel filters that were behind the passenger side fender liner. All you need to change the L5P fuel filter is a 36mm socket and a pick to change the 2...

    Plastic safe, diesel resistant thread sealant needed

    I have a Massey Ferguson tractor with a plastic fuel tank that needs a new fuel hose fitting. We have had trouble with this plastic threaded fitting leaking around the threads in the past. What thread sealant would hold up to the diesel fuel and not harm the plastic fuel tank? <img...

    Valvoline 75w90 Conventional (VV820)

    Does anyone have experience with Valvoline conventional 75w90? Would a conventional 75w90 gear oil shear faster or offer less protection than a synthetic gear oil of the same weight? I found a good deal on some (VV820) and I am thinking about trying it. It can be had for less than $2/quart...

    ST 75w90, what do you use it in?

    What are you using Supertech full synthetic 75w90 gear oil in? How long have you been using it? I bought 2 quarts a few days ago to change out the front differential in my sisters 05 Trailblazer, I haven't changed it yet. I'm considering using it in my 2017 Silverado 3500 HD in the front and...

    What Fluid in a GM Hydroboost?

    What power steering fluid would you use in a GM hydroboost unit? I know some guys use ATF and some say not to. The manual calls for GM Power Steering Fluid, part no. 19329450. The vehicles in question are a 2016 LML Duramax 3500 HD and a 2017 L5P Duramax 3500 HD. The PS fluid on the 2016 is...

    What is Viscosity Index?

    I've been looking around at a lot of different oils and ATFs. I think I understand the relationship of viscosity and temperature as it relates to the viscosity index. I have always thought that a higher viscosity index was better and would flow better than a lower viscosity index fluid, given...

    What vehicles are you using Maxlife ATF in?

    I'm using it in my 07 Tacoma's transmission (A750F) and the power steering. I've only done one drain and fill with Maxlife so far, previous services were done with WS. Future services will be with Maxlife. The drain fill with Maxlife was done on 4/2017 at ~80k, the truck now has 86k. I am also...

    Magnefine filters are metal now?

    Has anybody tried a new style magnefine yet? It seems that the old plastic/nylon style 3/8" and 5/16" filters have been discontinued and replaced with a metal canister type replacement. Has anybody used one or cut one open to see what the construction is like now? <a...

    Dexcool in a Yamaha Rhino?

    I'm getting ready to replace the failed stator in our 2011 Yamaha Rhino 700. You must drain the coolant and engine oil to get the cover off to access the stator. The Rhino currently has a 50/50 green all makes/models universal coolant in it. I have had no issues with the green antifreeze, but...

    Changing my oil too infrequently? PCV problem?

    I have a 2007 Toyota Tacoma with the 4.0 V6 (1gr-fe). It was bought in 2007 with ~3,600 miles, I used PYB 5w-30 for the first 30-35K at 5k intervals. Then I started using Mobil 1 5w-30 and later began using Mobil 1 5w-30 EP. I'll post a pic of the maint records, there are a few gaps in the...

    Off-road diesel, NPT thread sealant

    I'm putting a new fuel hose and nozzle on our 500 gallon off-road diesel tank. The hose, nozzle and pump outlet are 3/4 NPT, do I need to apply a sealant of any kind or will the fittings seal fine without it?

    Federated, grab some or pass?

    From what I've read it most likely comes from warren distribution, likely the same stuff as supertech. What cheap oil are you guys using/paying for it? A chain store local to me carries this oil and has it on sale through 12/31/17 <a class="lb-image-link" rel="shadowbox[796045a3c416328491]"...

    Which Lubegard, if at all?

    I'm gonna start using Valvoline Maxlife ATF in my 2007 Tacoma with the A750F transmission. I currently have a mix of WS and Maxlife in there, but will be doing an annual drain/fill with Maxlife. I've heard a lot of good things about Lubegard, but I'm not sure which kind to use. There are 2 types...
