Rotellat6 5w40 2*2.5 Gallon Case

I have a 17 year old Volvo TAMD41P-A diesel in my 31' recreational trawler. Prior engine oils for the prior owner (11 years) and me have been 15-40 dino oils, until I switched to full synthetic engine oil, also 15-40. Operating temperature dropped 5 degrees at standard cruising RPM of 1800 to 2200 (only one of two thermostats in place most of that time), the engine runs quieter and more smoothly. Based on research I have found, I know that my engine is running cleaner, with other attributes of reduced internal corrosion, less wear, etc. After installing 2 new thermostats, the engine runs precisely on specification for operating temperature through the full range of RPM, right up to wide open throttle, 3800 (end of the day 10 minute spike to clean the exhaust system ). Further, smoke when starting is greatly diminished to almost zero. I am completely satisfied that I am doing all that I can to accomplish optimal engine performance and protection with Rotella T6 over the last two years, and I am comfortable recommending Rotella T6 to boating friends with diesels, confident in the cost/benefit of using the best oil quality, grade and viscosity for my application.

After hearing and reading rave reviews on this oil, and reading posts about it on oil-focused sites and forums, I thought I would give it a try. Im running it in my 04 Grand Caravan with the 3.3L V6. Running a half-and-half mix of 5w-40 and 15w-40. Let me say this, my van has never ran so well just by changing the brand and type of oil I am using. It currently has 209k on it and runs like a top. I switched to diesel oil because it has a higher film strength, better wear packs, and better detergent packs than gas oil does. I want my van to run as long as possible. I am one of those people that drives a vehicle until the wheels fall off, so they say. Ive used other brands before and they have worked well, however, since changing to Rotella T6, my van has more power and response than I ever remember it having. Rotella and other Shell products will be my only brand now. Stocked up on quite a bit of Rotella in all its major types, T4, T5, T6.

I used to run this oil in my Victory Cross Country, but I did feel the clutch slipping from time to time. Like most Harley guy's, I was very finicky with how I maintain my bike. I purchased an S&S 124CI kit for my Road Glide and was waiting for the parts to arrive. I still needed to ride until then, but my bike needed an oil change so I took the chance because I knew how well my Victory ran with it, plus I was just trying to be cheap since I had to dump the oil anyway for the new motor build and I didn't have to worry about it slipping because I did not use it on the primary or transmission side. At the end of the day I'm glad I tried it and I love it so much, Im selling the 124CI and gonna be content with just a Cam upgrade. The bike runs so smooth, quite and MPG went up. Its like a brand new bike with 34k miles on it. I will continue to run this as motor oil and use recommended oil for the primary and transmission going forward. This product is the best thing the shelf.

Used T6 in my 2007 FZ1 since I bought it used about four years ago. I rev this bike to the Max, never had a single engine problem, doesn't run hot, uses zero oil in between changes. I understand that it shears easily in a wet clutch situation (as do many oils) so I change it as I reach about 1k or 1.2k miles that way the engine always gets fresh oil. It's cheap and not that hard to change oil and filter. I only ride for fun so I change it maybe a couple of times a year.

I been running this in all my cars and trucks, ATV for many years. My 2007 Chevy Cobalt I drive the most and it has 160,000 miles and I been running this oil since 60,000 miles, starts great in Minnesota winters and I never replaced anything except brakes
