I have been perusing this site and don’t find much in the way of comment (good or bad) regarding Mobil’s Delvac 15W-40 diesel engine oil.
From what I can tell, this product meets all on-road diesel engine requirements, it is available (at least for me here in the Houston, TX area), the manufacturer has a good reputation and it is performing well in my CAT 3126B engine in my RV. So far, in 7000 miles, I have added no oil to the engine in both summer and winter driving
Yes, I know, most RV applications put little stress on engines but NO oil added? This would seem to me to be a bit extraordinary.
Am I wrong or is Delvac just not that popular? Or, is Delvac just not a top notch product?
Also, can I safely stretch the factory recommended OCIs using this oil, say by 2000-3000 miles out to near 10,000 miles?
I’m anxious to hear your comments regarding this product and my application.
Thank you.
