Excellent channel, production value is really good 👍. Thank you for all the free knowledge you are sharing

Thanks for sharing also the transmission & differential oil change maintenance interval often get over looks

Hi Adam, I did valve adjustments on my 2015 Cascadia with DD15 at 300k first time and at 800k second time in the first week of this year. After that the MPG is down from 8 mpg to 7. Ask the dealer, they said its normal and it will get better. I want to hear it from you.

You're the best

Adam you are great machenic very skilled we didn't get like in WA one day I get a chance to meet you thanks for your helpful info

You make my life much easier brother Adam

Love your videos man I just purchased a Volvo with a d13 can’t wait to bring it over!

Ima be there soon my guy. Alot of people say good things bout you.

Am so excited about this.......

Replacing DEF filters are VERY expensive, you DONT have to replace them. You can take them off and clean them out with a high pressure washer until you get clear water coming out. Do NOT use any harsh cchemicals in the wash out but you can use dawn soap. that will not hurt the filter and that cleans everything to grease.

Wow... I noticed you always use mileage for service intervals....I always use hrs....every 200 hrs I change oil and filter, every 100 hrs I grease, every 400 hrs I change fuel filter, I also use a fuelpro filter on my ISX 550 which I change at 2/3 of the way to the top..black portion of the filter.. thanks for the vid!!

I live in Austin but I'm coming there for my trucks maintenance

Adam, top notch vid as always. What fuel/oil additives do you recommend? Do a video on oil/diesel additives and what you’re thoughts are!

Great content!.

Every time I get my baby out of their shop. There's smthing wrong with my rig, that's not right. I go bk n tell them. N what I hear alll the time out of the their mouths. WE DIDN'T DO THAATT... I kw my truck. SO plzz help me with my baby. I need a good Mechanic that's not gonna fuck me over or anything else and I see that you guys r legit on the video's.

Are all these recommendations exactly applicable to a Volvo D13 maintenance schedule? And if not, can you do one on the D13 please ? Keep up the GREAT work!

Could you do a PM video on a box truck? I have a 2019 Freightliner m2 106 with an isb 6.7 Cummins. 🙏 thank you!

Why I feel I have more power by using the Cruise control than just using the fuel paddle….if have the cruise on then I want to speed using the fuel paddle I feel like I’m driving corvette…but if cruise off …have no power

Turbo job is very expensive. What’s reason of fail turbo . And how can we care and take look how bad or good condition is . It destroys DEF box too . Teach us pls

Would u recommend a Volvo or a Freightliner for a first truck?

If you want to run longer oil change intervals say 50k to 75k which freightliner says you can do you must average 7 mpg and above and also don't change your fuel filters unless your fuel is hitting the full mark on the filter in the see thru canister otherwise hour wasting your hard earned money on these shops for extra pms you don't even need

I have a freightliner coronado 12.7 60 series mid roof 10 speed no def dryvan great dane trailer hauling 40k or less on weight mpg now is 4.5 maybe 5.0 any suggestions 🤔

Adam Good evening Is bad for the engine to run with Jake brakes during mont eagle Tennessee travel ? Thanks for your valuable answer Regards Carlos Aguirre 17 Februay 2021

Excelente

I drove 62 for a whole week and the best mpg I got was 6.7 so like wtf? I run the same 2 loads every week. One is 20k lbs and the other is 10k. Louisville to Jersey and then PA to Memphis

I have 2013 volvo d13 deleted def. My average fuel says 5.6mpg on the dashboard. but if im driving flat surface and not windy i can get 6 to 8 mpg, but if im on windy 8mph winds and above my fuel drops around 3,4,5 pmg and my truck feel so weak. That can be this issue.

I get hesitation on my 2001 freightliner century on my high side more when I’m loaded it hesitates and bucks in 8th & 9th gear more ... I let off gas and it stops ... what you think ?

I have a 2008 Freightliner cascadia not running well. No power

Whtts up mate what u recon more important the brand of the truck or the engine under the hood

Hey I got a 2004 freightliner columbia I was trying to wire in a electric fan switch and touched some wires to something hot and instantly truck started running bad check engine light came on do you think I blew the ecm?

Can you make videos about paccar engine please

Hello tat, i bought some used Nissan UD GH13 which engine of volvo d13 and seems like my trucks are using 600litres to make 860Km.. And is sounds crazy.. Because other semi truck are using around 450litres to make same mileage as mentioned 860km But mine is 600litres for 860km any ideas Trucks doesn't smoke at all..

This is for new trucks or doesn’t matter the miles ?you must do it for every “X” amount of miles … for example I got a truck at 300k so must do it for every X amount of miles doesn’t matter if it’s not new ?

Question I se see for sale a Freighliner with Mercedes Benz engine good to buy it’s ???? Thanks

At how many miles need to change engine air filter international lt?

So would you say 1600 to 1700 rpm is too high too consistently run a dd15 @ 75 mph plus my mpg is 7.8 have the d12 trand 2.47 rears . Also I hate when in automatic mode how it downshifting while eng braking turns 2300rpms i dont think thats safe .

Synthetic blend oil for freightliner good oil

Hello Adam I'm I qualified to enter even though I live in Jamaica 🇯🇲?

how to get better mpg on cummins isx 15 550 HP engine? please

nhìn garage và anh rất chuyên nghiệp

How does the doc gets clean?

do you have anything on d12 volvo

I am getting an average of 6.3 miles per gallon on my Cummins

EnG 1 spn 102 fail 18 any suggestions

Now the engine is purging when idling

Make sense buy old truck n change all parts rebuilt engine n trans.

How much for a valve adjustment on a dd15 like to come in today if you are available Adam 2016 WS

Why nobody wants to talk about paccar engines. I heard you replace every part around the engine leaving the engine intact with no repairs

Still having suit enter my cab my face is always covered in black when taking a shower

My takeaway from this as an o/o is to do the maintenance you’re supposed to do anyways. There was nothing new learned. This feels like a video you would see on a dvd after buying a new freightliner 🤷🏻‍♂️

Yo no soy mecanico. Pero tu estas mui verde Para ser mecanico compa. Una calibration injectors rings es 250.000 mil millas. Quieres economia en diesel nesesitas una trasmision 13 speed. Unos difereciales 3.36 Ration o 3.42 Ration unas yantas 11R22.5 tires y un buen motor un caballaje de 470hp. To 525 hp. Y esto te Dara economia en diesel y yantas

Slow tf down and dont idle is all u need to know

sure just change your def filters like it doesn't cost thousands of dollars

Delete EGR and DPF and replace with SCR/DEF.

More mileage..get a smaller truck

Get a truck no def system!!!!
