Oil & Fuel Mahindra 2555 tractor engine oil.

For what it's worth I use the Rotella T6 5W-40 in most of my engines.

BTW- most would tell you that 100 hours is roughly 1000 miles of use for figuring service intervals. So if you service every 300 hours that痴 only 3000 or so equivalent miles- that痴 an easy life for oil. OTR trucks and most cars have service intervals that are 3x or more that for the oil. I say all that to reenforce that we typically baby tractors when it comes to servicing. Yours (and mine) will be no different.....haha

I don't know how someone comes up with a 100 hours equaling 1000 miles.
I always went by 100 hours equaling in excess of 5000 miles, the old mechanical hour meters calculated hours with the engine at pto speed,
so 100 hours times 50 or 70 mph would be 5000 to 7000 miles.

My pickup has an hour meter on it,
with 60,200 miles on it,
it has 309 hours of idle time,
1668 hours of driving time,
total hours of 1977.
60,200 miles / 1977 total hours = 30.45 mph x 100 hours = 3045 miles/ hundred hours
60,200 miles / 1668 hours driving = 36.09 mph x 100 hours = 3600 miles per hundred hours.
I drive slow mostly on secondary roads, someone driving more highway and faster would have more miles per 100 hours.

All that to say I change most of my engines every 100 hours or annually.
My pickup is supposed to be every 7000, I do it at 5000 miles or under.

I believe a dip stick should be used for oil sampling, not just oil level. I worked a nuclear power plant for 29 years a maintenance mechanic. We helped the techs with oil sampling on a regular schedule for pumps, electric motors, valve operators and even diesel engines. These samples looked clean, almost like new oil. Yet, when the test results came back, many were contaminated with metal particles and other things. The testing lab could tell us what metals were in the oil and that would tell us if there was bearing failure beginning. The oils had also broken down as far as their lubrication qualities. My point is, the oil may look good to your eyes, but it may be trashed. Diesel oil can be ruined by combustion particles and they can be seen just by wiping the dip stick on a clean rag or paper towel. I believe if someone decides to not change their oil every 100 hours, you should at least change the oil filter and top off the engine oil level. I don't put many hours on my 2555, so an oil change every 100 hours is cheap.

You totally lost me on this? I never had to do this, in order to post as a new member, at least I didn't think I did. Your 2655 is about 99.9% like a 2555, so many of our post would be on interest to you.

After spending a couple hours writing up a step-by-step for the 50 hr maintenance, my thread could not be posted as I had not had 3 posts yet. My Step-by-step was my original post. Thank you for everyone's patience.

Did you get it posted?

I just looked and you did. I'll read it over, thanks!
