Cletrac HG oil change

[yorkyjer]

Before I worked the tractor, I wanted to change the Oil.  The Filter that screws on is a Napa 1103.  I went to Napa, and they could only get an 1105.  It turns out to be the right Filter, but of a different make up.. Not knowing what Oil to use, I wanted straight No. 30. Wal*Mart and surrounding stores only have 10 W 30.  I did find it in General Dollar. but at 2.85 a Quart. 6 Quarts filled the tractor.  My son is haulling trees with it now.

10W-30 should work fine, but you might want to read this http://lesfrickshun.com/ZINC__ZDDP_.html . Something I didn't know until recently, but all the oil rated SM or higher in the alphabet has low zinc/phosphorus that does not lubricate older engines with flat tappets as well as oils with higher zinc/phosphorus. You can buy racing oil that has the higher zinc/phosphorus and diesel rated 15W40 may have more. I use 15W40 in most everything, except hand-cranked engines or harder to start engines in the winter. There is a lot of information out there if you search for it.

Should I pull this 30 weight oil out and go to the other type ?  I can use the 30 weight in my Van, or wheel tractor.. The Cletrac engine is in beautiful condition yet, and has a lot of power.

No. The 30 wt is fine. You can use it all the time until it gets cold out and it becomes hard to start.

Unless you plan on using dual valve springs with 200lb seat pressure and buzzing it up to 8000 rpm, I don't think it will be a problem. You could use 15/40 diesel like Rotella, I think it still has a little more ZDDP in it. (or will until the gummint finds about it.)
