Delo 400 XSP SAE Heavy Duty Synthetic Diesel Engine Oil 5W-40, 1 Gallon, Pack of 1

Shipped promptly to Alaska. Packaged well.

My Briggs & Stratton 10HP 5250 running watt generator LOVES this stuff. Runs quieter, idles much more smoothly (no "stumbles"), and actually runs cooler according to my IR thermometer. I mix this gallong with one bottle of LiquiMoly MOS2 and the crankcase of the motor dropped 30 degrees F on both sides in 99 degree weather, with no breeze, sitting in the sun. Oil doesn't come out thin as water, unlike any number of fully syn 5w-30 and 10w-30 oils I've used (Mobil 1, M1 EP, Castrol EDGE, EDGE EP, Pennzoil Platinum, Valvoline Synpower, Quaker State UD, etc.). Spark plug also stays MUUUUCH cleaner and seems to last longer. Starte dusing this in my Honda GCV160 mower engine and it loves it too. Runs quieter, runs cooler as well (18 degrees F cooler), and is a lot smoother. Also, curiously, both are significantly easier to start. Both used to require multiple pulls on the pull string to start even after being primed. No longer. Both have started on the FIRST PULL since I started using this oil. Also, always use Stabil 360 or 360 marine in your gas. Always.

Despite reports online this oil has friction modifiers and is not serviceable for motorcycles, my experience with it has been the opposite. Clutch take up is super crisp with no slip, shifting is buttery smooth, and it holds up longer before it starts to sheer than the similar Rotella T I'd previously used. Very effective, durable motor oil that has no trouble standing up to my 15,000 rpm sport bike - and which delivers great shift quality as well. Only downside, it feels like it needs to get warmer before it flows nicely (and shifts start to smooth out) than the Rotella and Mobil1 I previously used.

I am using this in a Mazda CX-5 turbocharged 4 cylinder instead of 5W-30 that is specified by the manufacturer. It is SN rated and compatible with gasoline engines. Oil consumption is nil over 7500 mile changes and fuel economy may actually be better. Mobil 1 5W-30 went through the motor like crap through a goose.

Very good oil, this is my new oil for my 365,xxx mi 7.3 Powerstroke.

Great oil, Used in both my Cummins and MB Diesel Sprinter. I swear both engines idle quieter and run smoother when using this product. Superb oil at an Great price

Best price I can find on Delo 400. I run it in my Ford 6.0 and Kubota tractor. Great oil at a great price!

Great oil I use it in my Cummins engine. Good mileage and long change intervals. Great oil analysis results.
