Ingersoll oil

[D Shoe]

When I had to replace a line on my Ingersoll 4018,I noted the recommended hydro oil was 20w40. As there are no more Ingersoll dealers in my area, I checked at various auto parts stored and was met with blank stares. One even looked in a reference book and couldn"t find a listing to order it. I wound up using 15w40. This is for summer mowing. Anyone else out there have this issue and what do you use?

20W40 is still available from Ingersoll dealers but it's about 10 bucks a quart. That grade used to be popular 30 years ago but not today.

You can use 15W40 all year round providing your tractor is not exposed to temps falling close to zero F when it is sitting. Put the trans-axle in neutral, start the engine, push the travel lever into full forward and leave running for 10 minute or so at half throttle to warm up the oil.

If you live in an area where the tractor will not be used in temps lower than the freezing point, then 20W50 is a better choice.

If you live where the winter temps are almost always near zero F, then you might want to consider using 0W30 synthetic. However, as soon as the temps go back up above the freezing point, then switch back to 20W50 Dino oil.

This is a hydraulic system you are talking about? The oil they recommended 20-40 and was that a hydraulic oil or motor oil? There is a 20-40 motor oil and its DELO 710 LE. If it takes hydraulic oil I would use Lucas universal hydraulic fluid. Your best bet would be to call your Ingersoll Rand dealer and see what oils will work. They sometimes can give you several choices of oil to use.

This tractor has nothing to do with Ingersoll-Rand.

15W40, 20W40 and 20W50 are all MOTOR OILS. Hydraulic fluids are not multi-grade. These tractors require motor oil in their hydraulic system ONLY. That is what has been specified in the Owner's Manuals since 1963 and is still specified today.

Ok Tom but if he doesn't have a dealer he can get 20-40 motor oil from a Chevron dealer has it. Its DELO 710 LE which is a 20-40 motor oil.

710 LE is specified for marine diesel and railroad diesel applications. The question then becomes ... How readily available is this product?

It is not essential that he use 20W40. Either 15W40 or 20W50 or even straight 30 weight are all acceptable substitutions are are far easier to find at Walmart or an auto parts store.

Walmart has been known to carry Shell's Rotella T in 15W40 for many years. The issue here is that the OP should be using motor oil and not some hydraulic fluid that would create problems for him. Choosing an easy to find motor oil such as Rotella and for a reasonable cost, makes perfect sense to me and to many owners of Colt, Case and Ingersoll GT's.

Thanks for the input. As I stated, there aren"t any more Ingersoll dealers in my area anymore, I checked with NAPA and several others looking for 20W40 oil, which is what is specified for summer oil in my hydro tank. No one was any help, and since winter weight oil is listed as 5W20, I wound up using 15W40. This machine is for summer mowing and rototilling only. For winter I use a Speedex for plowing
