Take care of that 6.6 and it will never let you down ✊🏼

[@RichRebuilds]

This channel has been a huge inspiration for me with getting my first Duramax, Keep up the excellent work!

[@TruckMaster]

Definitely means a lot to hear it from you thanks

[@DK1102]

@Truck Master I haven't watched this video yet, but a recommendation like this makes me pay attention that much more! Just picked up my 2022 AT4 after 10 months of waiting so I'm wanting to take care of it

[@herrprepper2070]

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

[@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.

[@tomg8673]

You ever think of adding an Amsoil Oil Filtration System on any of your Trucks? Very slick set up with additional miles before oil changes / plus the additional protection. Love your channel!!!

[@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.

[@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.

[@nickjordan7095]

I love your videos. I’m a pretty new dramax owner (07 LBZ) and maintenance videos like this really help. I also runs amsoil in all of my vehicles.I think the quality helps the vehicles run better longer. I also had an amsoil oil bypass system installed in my duramax. I also got an air dog on your recommendation. Would you consider doing a transmission fluid flush video? It’s the next thing I need to do on my duramax and I want to make sure I do it right. Where are the jack points (I’m new to DIY maintenance)? Also does the scanner tool you mentioned in the beginning scan for engine light codes? Thanks a lot. Keep up the good work.

[@TruckMaster]

Thanks! The scanner will do basically everything you need it to for a diy guy like myself

Hmmm, 0w40 full syn oil since I’m a Canuck, Donaldson fuel filter up top, Donaldson blue for the oil, fleetgard filters on the lift pump, fumoto valve on the oil pan, Allison Oem filters. Optilube xpd when I remember to grab it or else stanadyne lubricity formula.

[@HuntsT]

I highly highly recommend you try Amsoil's SAE 15W-40 Heavy-Duty Diesel and Marine Oil. It's not to be used for post 2007 trucks with DPF installed. I have used it and according to analysis of several other oils compared to it that I've done and used it is definitely the best, even compared to other Amsoil oils.

If you would purchase an preferred customer package from Amsoil, you would get all their products at dealer cost. Also if you would purchase the bypass oil filter system you will save money with extended oil changes.

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.

[@kakarot82]

Can't go wrong with Rotella. I've run it in Caterpillar C 15s and C-15s for years and now in my L5P. Also Project Farm has a great video series on oil and shows how good it is. Love the videos. You are really talking me into an Airdog.
