Engine oil

[JeepHead]

I use T6 in everything. The way I see it is I can't afford NOT to do the best maintenance possible for what I own.

I used to use T6, now I use Valvoline extreme blue diesel synthetic. Not that T6 isn’t a very good oil, but since I own a truck with a Cummins and they endorse that oil, I use it in everything with a diesel engine.

We found out that switching lube oils at least in the Cats we ran in the fleet, switching lube oils would cause oil consumption for some odd reason so the shop stuck with Rotella 15-40 all the time.

Rotella T6 and Valvoline both offer high-quality synthetic engine oils, but Rotella T6 is known for its performance in diesel engines and its ability to handle extreme temperatures. Valvoline is well-regarded for its quality and is also known for its partnership with Cummins.

I'll use any brand that meets the grade, and is available in the weight I need. That's usually Pennzoil or Mobil, but have also used Rotella, Quakerstate, and Valvoline in the past.

Grade, weight, and amount seem much more important than brand, to me. I've seen engines fail due to incorrect fill amount, and even due to too-infrequent changes. But I've never seen an engine failure that could legitimately be traced back to one brand versus another.

A lot of people somehow don't undertand the difference between weight and grade, which is weird, as they have completely different number/lettering schemes.

I ran T6 in my Super Duty but thankfully I know longer require a diesel truck, my gasser 3/4 ton handles what I need now. Cummins is located about 45 minutes away from me and one of my best friends is an engineer there.

I always take any endorsement with a grain of salt because it might involve some sort of financial balance and or funds changing hands. I tend to discount 'endorsements' as a rule. Companies don't endorse another manufacturers product without some sort of financial benefit, least in my opinion, yours may differ however.

No doubt there is financial benefit for endorsements. But I also don’t believe that a major manufacturer with a great reputation would endorse a substandard product.

Agree! Asked my buddy about this and he said that Valvoline and Cummins work closely together on engine development and have for many years.

No synthetic or even semi synthetic oil is a substandard product today. In fact with the technology available and refining practices, they are all just fine with the exception of the bargain basement resqueezed stuff that TSC sells. Only good for chainsaw bar oil.

Like I stated, there is something monetary going on there that isn't public knowledge.

Like DDEC recommends a certain oil for their engines when in fact so long as the API designation complies, any oil that meets the requirements is peachy.

Kubota recommends their lubricants as well. All a game.

I believe that don't apply to filters, but maybe iit does and I don't know. SAll IO know is I use genuine Kubota filters but that may change as the last one I bought for my F20 mower set me back 20 bucks at the dealer the other day. That is a crazy high price for any filter in my view. I realize we have inflation but 20 bucks for a tin can with some filter paper inside, no way Jose'.

I seen a video not too long ago where they cut open the big name filters and a Kubota filter and inspected. The Kubota filter offered better filtration.

I also remember those cans and I had one of those metal push in spouts in my truck toolbox. I likewise remember going to full serve gas stations as a kid with my dad and the attendant always checked the oil. Frequently those 1960s era cars were “down a quart” and the attendant would add the oil along with refueling and washing the windshield.

an old friend of mine owned a full service gas station in the 60's. they always had an empty oil oil can with plunge spout on the shelf. when servicing, he recommended adding a quart to customers....he claimed he made more off that empty container than either gas or service
those were the days of Bardhol motor oil (sp) and dial your octane Sunoco

Not surprised. Some of those old service stations were less than reputable.

I can see where better filtration might be good for people that are too lazy to change their oil regularly but that isn't me. My oil never gets even dark brown in anything I own. Gets changed much more frequently as oil is the cheapest part of engine longevity there is, plus I always use the Nano-Borate additive.

 

[big bubba]

generally a good practice, but on your older M9000 diesels, oil prob gets dark sooner than need for 100-200 hr oil change? an analysis would answer the oil color issue.
having said that, i'm surprised that my Tier2 engine oil stays clear for quite a while compared to older diesels i've had.
overall though, you're right, good to change often & pay attn to the oil needs, etc.

Back in the 50's a block away from us the gas station had
an eve trough sitting on an angel in the back and every time
they sold a quart of oil the can would go in the trough and the
oil would drain into a bucket

No reason that you can't go from conventional, to synthetic, then back to conventional.

Now sometimes you are required to use synthetic. DEF for example. Basically you've got conventional peepee that comes from organic creatures, and then you've got man made synthetic peepee that is made in a lab or foundry or whereever synthetic urea is made. I mean why would you rather breathe in peepee fumes as opposed to some carbon emissions? But no putting a bucket under a horse or cat will not net you free DEF. Always wondered why H2O wouldn't work to drop floating carbon emissions the same way it does pollen.?.? I mean DEF is 2/3's H2O, and 1/3 peepee chemical urea. I'm sure spraying man made peepee into a hot exhaust system is necessary, and in no way a money grab by sick, twisted, rich, evil, lucifarian elites getting satisfaction abusing us common folk. This is why so many of us cap our TIER4 tractors at 75 HP. We do not like peepee exhaust fumes.

in regards of going from long term conventional gear oil, then to fully synthetic gear oil, i have had to replace almost all the seals on transmission, transfer case, & rear differential on my high mile 4x truck. i've gone back to conventional gear oil for the vehicle, but always use full synthetic engine oil & have for nearly 300k.
& yes, those seals probably lived out their life anyway,
