Tank Oil Change

[Barryh]

I changed the original 5w30 to Mobil 1 15w50 and there was a big difference. I was always getting stuck without spinning the wheels, now I rarely have a problem. I do keep the PT in a garage which rarely gets below 60.

Hmm that's interesting Bob how long have you been running the 15w50 ?

YMMV, of course, but...When it comes to older seals, I wouldn't worry about a viscosity change. Changing all of the oil to all synthetic, or adding some huge amount of additives might give me pause, but even then, I wouldn't worry about it. Most of the stories of synthetic oil leaks from cars that I have read have been from very old cars, which were made with much higher tolerances, long miles (and therefore deposits and wear), and thus very, very, old seals.

All the best, Peter

Your probably right, I may consider a 50 like Bob and Moss but going with regular oil this time around. I know I have fine metal particles in my oil tank after checking the magnets. So I will go with the less expensive Dino this time to flush them out. I may revisit the more expensive synthetic later down the road.

I suppose I could be pre-emptive, inspect the oil, and do an oil change if neccessary, but my guess is if I do that, I'll soon thereafter bust a hose and lose my oil investment. So, I'm thinking about just maintaining the course, doing better hose inspections, change any damaged ones ASAP, etc... and wait until a catastrophic failure to do a total pump/hose/wheel motor, and oil change if needed.

I hate to fix something that's not broken yet. I'll just keep up with the PM (preventative maintenance) program and see how it goes.

Agreed.... In my case I need to recharge the tank with fresh oil, I may consider trying the 10w50 also .. Like you said that's when I'll bust a hose ... Such is life.. :laughing:

Not long, about 15 years.

Just to be clear, I never have to start it below 60 degrees, so I don稚 know what it would do. I love the extra wheel motor torque.

Gotcha my garage is not heated..

A heated garage will definately help with starting issues and 15W oil VS 0W oil, however, once it gets warmed up, and then hot, its the high number that counts.

OK ordered 10 gallons of Mobile One 10w40 for in my tank. Probably do the change next weekend. Any advice or other tips on how to flush out the tank to remove bottom sludge before I add the new oil? Of course I know how this goes. After I replace with fresh synthetic I'll blow a hose .. So be it , old machine I plan to keep so I want the best in the tank to help prolong the pumps. I also ordered a NAPA 1551 oil filter as suggested from the Power Trac Parts Cross Reference Thread. Anyone using this filter, thanks.

Next up, Mobile one synthetic engine oil for the old Kohler new plugs plug wires ... Then an adapter plate to convert the old 3 pin for newer attachments .

I'd probably use rag to wipe out the tank then go back to it with something like kerosene and rags. But if you really want it clean there is an automotive solvent then you use soapy hot water to wash it off and out. Dry it well and that would be pretty clean.

Which Kohler engine do you have in there? I know on mine, I can't just order plug wires. I have to order two entire ignition modules. The plug wires are permanently attached to those.
