I've never heard of using engine oil for hydraulics. Maybe it's a thing for small equipment or something. Everything we have gets John Deere hydraulic oil.

Yes, some hydraulic systems use engine oils for convenience as in some parts of the world is hard to find hydraulic oils.

 

68 AW stand for the ISO viscosity grade, AW means Anti-Wear. So he used a generic hydraulic oil...

 

Follow the owners manual...............

Some Exmark and probably Toro commercial grade mowers call for Mobil 1 motor oil in their hydro systems.

he has been running the hydro fluid for more than 15 years now in the winter I do notice when it is very cold it is super hard to start even when the block heater is plugged in is this due to the hydro fluid being thicker than 10w30 motor oil? how do I flush the system of the hydraulic oil and replace with motor oil without mixing them?

      Whoever greenlighted the work truck matte black front bumpers on every trim but the AT4X should be fired!  I was hoping that was an AI mistake, but just realized they were on every model of the 2027 Silverado too.     Some parts of the interior do look premium, but the Denali Ultimate dashboard looks like an afterthought.  At least they appear to have lost the microfiber the high end Silverado models showed, but the '27 High Country dash looks better than the Denali.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

      - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.
