Oil analysis has some value. However, when I sent in an unused sample of Redline (synthetic) 15/40 for analysis it came back as highly oxidized. It was honey colored unused oil straight from a just opened bottle. A search online will show that several labs will tell you that Redline...

Well, he does speak of EGR and Exhaust gas treatment (DPF), so I thought he was seeing many stock trucks that haven't been deleted and are not chipped or programmed to spray more. Still, good point, because if they are chipped/programmed to inject more fuel, you'd be crazy to keep following an...

Interesting read here from a diesel tech. He probably hadn't worked on many 2019+ when this was written, as it was written in 2020. He generally disagrees with manufacturer recommended OCI and says that he has seen some oil-related failures. He does confirm almost all of what John said, and...

The CGI sounds a bit fragile in relation to the oil viscosity. Top end requires thinner oil. Bottom end can tolerate oil viscosity down to 10/30. The rhetorical question at hand is what happens when the oil viscosity changes as the emissions system goes through several active regens? I would...

I had a 7 year extended warranty and it was under the extended warranty and the emissions warranty, but since my 3 year manufacturer warranty was up, those other warranties were not good enough. They charged me labor for the emissions computer update. I was told by a former Ram diesel tech...

I have the Amsoil bypass and use the BP 90. The BP 90 stays full of oil and it contains about a quart. However, the full flow (I use Amsoil/donaldson/fleetguard) will allow the pressure to pull about half a quarter back into the oil pan. So, once it cools down, you likely have a half quart...

Might be a bit off topic. Those automatic transmissions on those new city busses sure don't sound very efficient. They make a whop whop wop wop when slowing down, stopping and starting up again. Maybe it isn't the transmission, but I can't imagine what is making that noise. Probably...

It is likely an optical illusion if you are going by the def gauge which is non-linear in the way it moves from full to empty. You likely didn't get gauge movement until the tank was drained down to 3/5 tank or just above a half tank while towing. But just because the gauge didn't move...

Wouldn't apply to you, but since I have a 2013 with the dual radiators, I carry a lower radiator hose. Changed out the upper one with an aluminum wye "Y" and regular hoses about 6 years ago. I also carry a spare hydraulic clutch mechanism, a spare serp belt, and a few other small items that...

Yep you can fertilizer burn your grass.

I'm always a bit nervous about those types of mistakes. Dang, the ethanol that is in the gas would kill the fuel system through rust and lack of lube.

Pretty sure they don't look at any of those 80+ things. So I just ignore that paper and do it myself.

This may be related to the relay, but I remember Cerberusiam speaking about a combination of a ground path fault possibly causing the grid nut to conduct electricity and the EGR bringing hot unburned gasses. Not sure about specifics on the ground path fault and if it is a fault in the...

Going to correct this post. I looked back through what paperwork I kept (cleared out some paperwork when warranty expired) and discovered my memory failed me. It wasn't the paperwork that didn't match the work performed. The paperwork was mostly accurate, but what was uploaded to my Ram App...

I had a good experience at Sam Leman in Peoria, IL. Didn't ask them to lube the front drive shaft, but they did and noted it on the paperwork. It was when I asked them to change the differential fluid in both differentials. However, there have been a couple times here locally that when they...

Anyone ever notice that if you take the truck in to the dealer and have more than one thing done, they don't list on the description all of the things you asked them to do? Sometimes I think it is so if they didn't do it well, they don't have a record that they did it. Even though they swear...

What is nice about the manual G56 is that the EB engages at 6 mph in first gear.

Yeah, I don't shop at Walmart, but bought some batteries a couple of years ago at Advance Auto. They asked me if I wanted the ones that have 3 year warranty or the ones that have a 4 year warranty. I believe the 4 yr warranty ones were AGM and had terrible reviews, so I bought the ones with a...

You appear to ask 2 questions... 1) why not use 15w 40? 2) why not use full synthetic? Different people have different answers. Some believe that paying more for synthetic doesn't provide a cost-benefit advantage. I think everyone should use a 15w 40 synthetic, but I refuse to badger them...

The #6 was a baseline on redline 15w 40 diesel oil. I discovered in some research online that Redline often gives false positives for oxidation. So, I wanted to see what an unused baseline sample would give as a result after getting an unsettling report after a 8000+ mile trip. I am posting...
