Best kind of oil??

[A DeWitt]

Just wondering if there is anyone out there running something other then 30 wt non detergent oil, I was thinking about maybe 15w40? The tractor is a 1948 Massey Harris 22

Unless the engine has recently been rebuilt, I wouldn't hesitate to go to 40, especially during the warmer months.

It should give you better compression and coat worn parts better - and increase oil pressure if your pump is getting worn.

So switching from 30 wt to the 15w40 should help the engine then? I just wasn't sure about going from non detergent oil to regular detergent oil.

Use Non-Detergent if you want sludge in your
engine !

Another one of those myths that say if you run non-detergent oil you can not switch or it will clog things up. Ya it may break a bit of it down but the filter will catch it and be goner in one or 2 oil changes

Run detergent oil. The weight depends on the temperature where you are and the oil pressure of the engine. Most engine wear occurs at start-up so a multigrade would be fine.

I use 30wt detergent oil in all my garden tractors and mowers. My garden tractor is 42 years old and the engine has never been rebuilt. It's used hard when plowing the garden Spring and Fall. Hal

Nope, 15w-40 in everything.

I run Chevron Delo 15w-40 in everything . Grandad ran it, dad ran it, I run it.

I believe the myth that going from non detergent oil to detergent oil creating ANY problem is an old wives tale. This opinion is based on 3 generations working and playing with old tractors.

I changed the oil and filter last night, I went with 15w40 and Lucas oil stabilizer. Oil psi is higher then it's ever been, thanks for all the great advice. Alex

A lot depends on the temperatures you operate at. I live in Western Montana and we have three tractors, two diesels and a gasser. I tried using 15W40 in the gasser(only oneS AE Grade oil to buy for ag equipment and diesel pick up then) and I noted it was harder to turnover in the winter months so I went back to using 10W40 in it.if you live in a mild climate and use your tractor in the winter 15W40 will work for you.

Can't go wrong with Shell Rotella T1 straight weight. There are some things a monoweight can do that a multi-weight can't.

Only a fool would use non detergent oil in anything.

I sure wouldn't agree with that statement.

Plenty of applications have guidelines that recommend a non-detergent oil, like air compressor pumps, lathe gearboxes, some hydraulic apps, etc...

A ton of manufacturers put out a lot of different kinds of non-detergent oil...
