Engine oil change Interval Jd 3520

[Beechboy]

Morning Folks
My 2010 JD 3520 engine oil was recently Serviced with Synthetic, has anyone changed to synthetic and extended their oil change interval, and is it Recommended ??

 

[davesl708]

I changed to syn a few years ago. I have not extended the service interval even though some of the manufacturers claim extended life.
I don't think the oil can stop other contaminates getting into the oil so the long it is in there the more contaminates build up.

Thanks for your input !!

the reason i changed to syn (rotel t6) was not for extended change interval, but for cold startup properties.
beyond that, i go w/100 hrs or annually, which ever occurs 1st best regards

You could go for more hours, but the weak link is the standard oil filter, if you go xtended hours change also the oil filter to one for more hrs

Me, personally, I just change oil every fall irregardless if it was a conventional to the best synthetic on the planet. I don't let anything sit in a sump for more than a year, and I usually don't rack up enough hours to change more than once a year. Condensation can be an issue and can affect acid buildup in an oil over time, so I am on the one year limit rule. Only a few quarts of oil and a filter, not like having to take out a second mortgage to change the stuff.

At least annually is good but 100hrs is a waste of oil. I know oil is cheap machines are not but most diesel equipment has at least a 200hr recommended change interval. I have some diesel equipment that gets 100 hrs on it every 9 days. I sure don't change the oil three times a month. Sometimes my semi gets close to 100hrs in four days. When it is cold and I am sleeping in it I don't turn it off for days on end.

Agree. If one is really racking up the hours in a year, 100 hrs is not necessary. My HD diesels are getting 400-500 hr oil changes, but they rack up enough hours in a year to go thru 4-5 oil changes. With the quality of oils today, I would place my lower limit at 300 hrs minimum or one year maximum.

I do shut off my semi daily, as running a Webasto bunk heater is a LOT cheaper than running a motor. 1/8th gallon of diesel for 10 hrs vs 1-1.5 gallons per hour to idle the truck? No brainer. But I am paying the bills.

This seems like a good rule. I generally change mine once a year or every 70 hours since I don't mind changing it. I don't even care if it is too often. But I agree with others, I think if you are using good oil and filter there is a pretty large tolerance of what you can do 70 - 800 hours for some guys who actually make a living with a diesel. A lot of times the guys who put lots of miles on before an oil change have had oil tests done to ensure the oil isn't breaking down.

If I put on maybe 100 hours a year and it is recommended to change every couple hundred hours or yearly, am I better off changing the oil in the late fall or the spring before the mowing starts? There is not much use after November.

 

[bdog]

I would change it in the spring so you can start with fresh oil before the heavy use season but I don't think it matters much either way.

I do mine in the fall so I'll have nice clean oil in it's best state for all the cold weather starts it will get.

I can agree with that logic. My reasoning for the other way is acids build up and oil deteriorates over time so if you change in the fall your oil will be getting older and worn by the time your heavy uses season rolls around. In all reality it probably doesn't matter much either way. I have a ton of things with engines and sometimes something that doesn't see a lot of hours slips by and goes over a year without an oil change and I haven't had any problems yet.

I'm in NE. What makes you think winter is my low use season?
