Hi, all.
2019 Mahindra 4540 with 230 hrs.
I changed the engine oil at 50 hrs. and refilled with Mahindra 15w-40 upon my dealer's recommendation.
Today at 230 hrs. I drained the oil and replaced with Chevron/DELO 5w-40 synthetic to help with cold starts. It's what I should've used when I serviced it at 50 hrs.
Anyways, when I wiped off the drain plugs I noticed what looked like a buildup of sludge around the plug and crush washer.
After removing the sludge with a pick I found it was hard, brittle, and varnish-like.
I reinstalled the cleaned plugs and refilled with the 5w-40 syn, tractor runs great and seems noticeably smoother and quieter at idle. Is that buildup of varnish on the drain plugs something I should be concerned about? What would cause that? Should I be worried about varnish buildup in other parts of the engine?
This occurred using dealer-recommended Mahindra engine oil with 180 hrs. of service life.
I'd appreciate any thoughts or opinions you might have. Thank you!
