Delo SAE Heavy Duty Motor Oil 30W, 1 Gallon, Pack of 1

Quick shipping and seems to be helpful for a old worn golf cart engine.

This is the correct oil for many 4 cycle lawn mower engines; please check your manual for the correct oil on your mower. The oil is of excellent quality and buying it in this larger package offered a big savings over buying the OEM smaller bottles. My lawn mowers are running smoothly on this oil.

Have used this with gas and diesel tractors. No problems to date.

Using on a 3.0 L boat engine that requires 30w. Works great and keeps internal engine clean

so far so good in the briggs lawn mower engine that calls for sae 30 oil..there are several oil changes in this compared to constantly buying quarts at the store. i much prefer sae 30hd (high detergent) over 10w-30 for the lawn mower since it only sees the higher temps of spring/summer/fall and small engines really need the high detergent package to prevent sludge and particulate damage. if you are unaware diesel oils are typically high detergent to handle the soot.

Purchased for small engine and lawnmower oil changes.

Great delivery

I build custom Detroits and Cummins engines, and older GM and Ford diesels. I use this or Rotella through spring and summer on the 4-strokers (32/0 degrees and higher), and it never fails. Excellent product. But remember: you can't switch back and forth between synthetic and mineral based oils because it damages the seals. Some say that doesn't happen anymore. I assure it still does, over time. You can switch to synthetic on a engine with up to 5,000 miles with no problem. After that? I wouldn't risk it. And for 2-strokers, you need a minimum of 40 weight during spring and summer. :) Happy clattering!
