I recently acquired a Ditch Witch R40 equipped with the Deutz F3L912 air cooled diesel engine. I'm unsure about the appropriate weight of engine oil to use. The local dealer recommended 10w-30, while the online manual on their website suggests 30w. I have always used Rotella 15w-40 on diesel engines. This machine has both gas engine models (Wisconsin VG4D, Continental F163) and diesel engine models (Deutz F3L912, Perkins D3-152), making it challenging to determine the correct oil weight. Any advice on interpreting the online manual or clarifying the dealer's recommendation would be greatly appreciated.
When it comes to choosing the right oil for your equipment in temperatures above 40 degrees Fahrenheit, it's important to pay attention to the manufacturer's recommendations. Whether you're working with a Wisconsin or Deutz engine, it's crucial to use the appropriate grade of oil. While 30 weight oil is often recommended, it's essential to note that it is not the same as 10w30. You can confidently choose between 10w30, 30 weight, or 15w40 oil, but many prefer using 15w40 for optimal performance and protection. Remember to always refer to your equipment's manual for specific oil recommendations.
When choosing oil for your vehicle, it is recommended to opt for a 15w-40 Diesel Engine Oil (DEO) over a straight 30w. This choice is crucial for optimal engine performance and longevity. While a detailed explanation could be provided in a white paper, it is suffice to say that the former option is more beneficial.
Delmer stated that the chart indicates using 30 weight oil above 40F, but it's unclear if this applies to Wisconsin or Deutz engines. He prefers 15w40 over 10w30 or 30 weight oil. Coaldust recommended using 15w-40 DEO instead of straight 30w due to specific reasons. They both lean towards using 15w-40, but the choice between conventional T4 Rotella or synthetic T6 Rotella 15w-40 for an air-cooled engine is up for discussion. Some suggest that synthetic oil may be a better option for air-cooled engines.
I am grateful for your quick responses and assistance. Thank you both for your help!
I rely on Rotella synthetic oil 15-40 for my 75hp Deutz-powered Vermeer plow.
