It’s all about common-sense maintenance. I run three diesels… A 1984 GM K2500HD with 6.2 diesel (bought new, 325,000 miles on it)… a 2007 Jeep Grand Cherokee with the Mercedes diesel (bought used), and a 2009 GMC 3500 xtended cab with Duramax (bought new, 194,000 miles). The Jeep is my wife’s vehicle, the two GMC’s are work trucks on our place here in NW Wyoming. Best maintenance advice I ever got was from the head mechanic where I bought the 1984…”Never put it in gear until she’s warmed up… use the best oil you can afford… and use Power Service in every tank of fuel.” I’ve followed that advice religiously. When I bought the 2009 Duramax, I put 500 easy miles on it, then took it back to the dealer and had every filter and bit of fluids (except coolant, brake and power steering) replaced with fresh… in order to flush out any debris left in the truck at the factory. I then put 5,000 miles on it, changed everything again. Another 5,000 miles and repeat… except that third time, I used all AMSOIL full synthetics… differentials… engine… transmission… transfer case… and the AMSOIL 20-micron, 25,000 oil filter. I get a lab analysis once a year… change the Allison spin-on transmission filter and the stock GM fuel filter at every oil change. (5,000 to 10,000 miles… depending on lab results). The vehicles are always serviced with AMSOIL synthetic oil. Euro blend for the Jeep and 15w40 Max Duty for both GMC’s. Your results may vary. I keep everything bone stock… except for the perceived weak points of the 6.2 that I rectified… Dual oil filter setup, a Banks intake/exhaust and an upgraded NOS GM fuel filter setup made for mid 90’s diesel vans.

[@chrissmith8769]

I found another way to check injectors if you don’t have a scan tool. Turn the truck on and once it’s warmed up, slowly rev the motor up to about 2500-3000 rpm then let off the throttle. If the rpm gauge goes down smoothly then the injectors are good. If the rpm gauge goes down then goes back up a little bit it’s a sign that one or more of the injectors isnt working right and still spraying fuel

[@TruckMaster]

I like your thinking

[@mikegarcia7452]

Thanks for the tip. I was stressing not having the scan tool

[@mikegarcia7452]

@@TruckMasterhow many miles between oil changes with amsoil?

[@great2c4me]

⁠I think it's 10,000 but you could always take an oil sample through cat or horizon / Polaris laboratories. Go on their website, they'll tell you what wear metals are displaying and what kind of fuel dilution you're dealing with.

Lucky you. I’d love one of their transfer cases although I will buy one from him, you can just drive over! Definitely a must do on these trucks

[@Whiskeybende]

PPE +1 oil pan! Best investment I did for my Dmax! Flat bottom vs the hump in the stock oil pan which holds 16oz of dirty oil that will never drain out. As far as tie rods I run Rare Parts inner and outer tie rods as well as the Rare Parts pitman arm, idler arm and the pisk kit to keep the center link from rotating.

[@deadmanwalkin9912]

[@TruckMaster]

Thanks!

[@Maximus-bu6eg]

Only add to the video. Pre fill the new oil filter before you install. Reduces time the motor goes without oil being pumped through. Reduces dry start.

[@charlesswearengin2404]

What's your opinion of putting Seafoam in your crankcase, for sludge reduction. O8 LMM 117,000. I basically use Seafoam to fill the volume for my oil filter. I bought a tuner, and more than doubled my mileage and power. Its stock, K&N breather filter, removed muffler at flange and 5" to the back. Lift pump is in the near future Air Dog, because of frame rail mounting.

[@BeyondHighHopes]

I suggest looking into getting a Fumoto F106N FN series drain valve. You got plenty of other fancy stuff and seem to have overlooked this little gem. The valve eliminates the need to carry an oil pan while on the go and practically eliminates the risk of making a mess during a change. It is particularly useful for people like me that are towing trailers full time and find themselves doing oil changes at random places because the road trip never stops. Thanks for the video and glad to see the channel is doing well!

[@T18skyguy]

I second you on the Fumoto drain valve. I ended up installing one cause when I would drain oil on my lift, the oil would splash over the drain pan screen and onto the floor. The Fumoto makes it drain just right. So easy to change the oil now. No more wrenching the pan bolt.

[@MrPhatkatz]

Thought I would share that Amazon has a bundle deal on the A/C Delco oil filter, fuel filter and Allison transmission filter bundle deal $66 and some change. Where AutoZone wants $59.99 just for the fuel filter.

[@joe8319339]

Buddy like the vid. Please change your oil pan with the PPE High Capacity, Cast Aluminum Oil Pan #114052000. Add a magnetic drain plug. Does wonders. Plus remove the factory fuel filter / primer housing all together. You have a lift pump. It's not needed. M.

[@Gamullikin]

To be honest. I've never been into Duramax diesel trucks until I started watching your videos. Im looking into buying a duramax or powerstroke. Both are nice trucks

[@TruckMaster]

Thanks that’s awesome

[@Radar8717]

Me too and now mine is a shit show in pieces lol

[@crambow]

7.3 power stroke or 5.9 / 6.7 cummins all other choices are bad ;)

[@rickydavis2267]

Buy a Duramax or a Cummins seeing and hearing of the powerstroke and they issue it not good.

[@justinteel7172]

Just bought my first duramax 2016 Chevy 2500 today and this video helped with what I need to get and how to maintain the truck.

[@brandonbarrentine7763]

Great info dude, don't forget to check oil level after running the engine to fill the new oil filter and check if you have directional tires, if they are directional then they don't switch sides during a rotation.

[@ipotch1]

I run Amsoil 15w40 heavy duty diesel and marine oil. The guys at my heavy equipment shop say there is less emission additives in this oil and better for the engine. Obviously I took their word for it and I don’t have facts about it. But I’ve been running it in my LBZ for two years now and she runs strong with 235k miles currently.

[@antonioreyes8209]

Great videos!! They sure do help a lot due to me being a first time diesel owner. Bought my 2003 2500 hd 4x4 with 93k miles. So stoked!!!! Keep the videos coming. Great job!!!

[@Grannypannies]

hope it came with newer injectors

[@ermannodangelo4087]

I noticed you had transmission filters on table but didn’t show changing them. How often would you change them and do you use Allison filters or aftermarket also which fluid do you use. Thanks

[@connorchecketts]

Another tip is if you don’t have a high pressure fuel rail 07 and older basically pre emissions. You can fill up the fuel filter with ATF and it will clean the injectors.( DO NOT USE ON A HIGH PRESSURE FUEL RAIL). But it’s a trick I’ll use as a diesel mechanic.

[@everlysuniquetimbersawshop]

I just bought a 2008 with 233,000 on it. Does it have a high pressure rail? Any advice on how to clean the injectors and keep everything happy?

[@connorchecketts]

@@everlysuniquetimbersawshop if it’s the lmm then yes you do. If you do have one I’d recommend getting a diesel fuel treatment and just running that through it. (NOT gas treatment). On a lot of those because you have a DPF and EGR there’s a lot of very sensitive components you don’t want to send anything other that diesel. Other than that there’s not much you can do for the injectors.

[@connorchecketts]

@@everlysuniquetimbersawshopanother thing is keep up to date on filters if you’re sending dirty fuel through your injectors. You can kiss your injectors goodbye.

[@everlysuniquetimbersawshop]

@@connorcheckettsit has been deleted. I’ll buy some hot shots and will use it every fill up.

[@connorchecketts]

@@everlysuniquetimbersawshop then imo you’re doing everything you can. I still wouldn’t use atf just because of the hpfr.

Great information, i recently got a 09 and it has wix on the fass and a wix on the factory fuel filter and has no water sensor its just the canister. I was wondering if you knew that part number to that filter option. I can't get part number without removing and haven't researched hours but awhile. I figured id be ok replacing them before winter and eventually putting the horseshoe hose on to delete it. Im use to old 7.3 powerstroke with leaky fuel bowl and everything, i question the fass filters being EXTRA exposed down there in sub zero with blended fuel and treatment even idk . Would i still need to pump the plunger on factory to prime with the fass on there? Also wondering what intervals to change little canister filter on trans and if that has a wix option. Any help is appreciated as i know i can eventually find answers but figured you or some viewers may be able to steer me in the right direction. Sorry for writing a book and using punctuation when I felt like it. Thanks for all the information you know your duramax for sure.
