Shell Rotella T 550045348 T5 15W-40 CK-4 Synthetic Blend oil , 1 Gallon.

good price and quality

Good engine oil. Does the job.

Great price

I have used Shell Rotella for years in my semi trucks without a single internal problem. Based on my success with Rotella in the past, I decided to trust Shell Rotella T5 Synthetic Blend in my Diesel pusher motor home. As the third owner, Im not sure what type of oil the previous owners used, but the synthetic blend seemed like the best choice. I didn't notice a difference in noise, performance, or change in operating temperature but it did seem to run a bit smoother. For a couple of dollars more per gallon over the conventional oil, its worth it

Great oil
