Verified Purchase

I have been using Delo oil since the ********* when I worked for Standard Oil before it became Chevron. I have been using Delo 15-40W in our RV Diesel Pusher since our purchase in Mar *********. I do my on servicing and I don't ever recall having to add oil in between servicing. I also use the Delo 15-40W in our ********* RAM Eco Diesel. The Cummins factory requirement is 15-40W and I switched the Sen-Blend formula in both vehicles when it came on the market several years ago. So far, both vehicles are working fine.
