The concern about start up engine wear is why I run Prolong in all of my engines. Also it can be run in the hydro oil to help with the same issues.
I agree, but I would feel that an engine knocking (piston slap, wrist pins, etc.), would have given up by now. If it's not low rpm rattle then it's time to see the dealer.I think he means he hears a "dry knock" because if whatever sound he's hearing goes away once the oil light goes out, it's certainly not normal diesel clatter he's referring to.
Exactly, I'm aware of the normal diesel engine sound. The 'rattle ' on start up ends as soon as the low oil pressure light goes out.I think he means he hears a "dry knock" because if whatever sound he's hearing goes away once the oil light goes out, it's certainly not normal diesel clatter he's referring to.
I'm aware of the normal diesel engine sound. The 'rattle ' on start up ends as soon as the low oil pressure light goes out. The engine then sounds normal. It's like the first start up after an oil change, you know by the sound the engine makes that the oil pressure came up.The oil pressure will sometimes take a few seconds after start to register best pressure.
The rattle is not because of the oil pressure. It's because the engine is a diesal and that's the sound of small diesal engines at low rpm..
I would think it has an anti drain back valve, so it may be worthwhile to replace the filter in case it's not working. Then switch to 0-40 synthetic like RalphVa says.After my 1023e has not been operated for a extended period of time it takes about 3-4 seconds for the oil pressure warning light to go out on start up, and the engine does 'rattle' letting me know that it is thirsty for oil. That being said if the machine is used daily or every other day it seems to be fine, is this considered normal? Does the engine oil filter have anti drain back? I'm using 5w40 Rotella. .
I run 5w40 Rotella and I’m not seeing it any longer than usual either. Truth be told if Deere manual states it’s safe to use other grade level and it’s base on demographics (temperatures) location it shouldn’t caused no issue unless something else is off. I would recommend calling the dealer and ask if it’s normal and if it’s a major concern to you, and the tractor is still under warranty, I would get the dealer to check it out. Otherwise maybe someone with better experience will chime in.4 seconds sounds too long before the light goes out, it's not hydraulic lifters because these engines don't have hydraulic lifters, they are adjusted manually.
My 1025 has 15w-40 in it and it never takes more than a second for the oil light to go out.
