Shell Rotella T4 Triple Protection 15W-40 Diesel Engine Oil, 2.5 Gallon

Few years ago a tornado came through our area and damaged a lot of power lines and a power station that fed all of the lines to my parents house. They were without power for weeks. My dad was very sick and few months from passing and my mom didn't really know much about small power equipment. So I would set the portable predator generator up, fuel it up, my mom would just fill the generator back up and immediatly start it again. Every few days I would stop by, bring more fuel, and change the oil with this oil. When I would check the oil collection pan I never saw any flakes or anything, which is rare for a splash style engine with no filter. You will usually see a little metal flake. Nothing. For two weeks the generator was only shutdown to refuel or change oil. The spark arrestor was nearly stopped up, but I cleaned that out, put a new plug in, changed the oil, and put it back in storage. During that time period it never was low on oil, and doesn't burn a drop to this day. I attribute that to a good heavy duty oil. I keep about 6 jugs on the shelf at all times just in case I got to do this again, thats how much I trust it.

This is the fourth time I have purchased this oil. I use it in my diesel rv. No complaints and the price is right. I will be buying again.

Excellent diesel engine oil! Provides strong protection, reduces wear, and keeps my engine running smoothly. Great for heavy-duty use with reliable performance in all conditions. Highly recommend for diesel owners!

Great price for this day and time.

Great oil for motorcycles, maintains viscosity for a solid interval.

Just what my car needed.

Handles high temps, prevents sludge, and extends engine life

Only think I will buy
