Customer Reviews for Shell Rotella ROTELLA T4 TRIP 128OZ 15W40 MO (Case of 3)

An excellent product for the gear box of your off-road motorcycle. You get a gallon for the price of a quart of boutique oils. I have run Rotella for 15 years and never a problem. I get long clutch and bearing life.

My 1994 F350 7.3L with 270k seemed to idle a little rougher running T3 but when I took the leap on running T4 I couldn’t be happier. My diesel runs like a brand new truck and no more leaking! My truck has been brought to a new level with Shell Rotella T4 15w-40 ! Very excited to see how she runs the next 3 to 4k miles ! Definitely an eye opening experience in my journey with this truck .

I and many others I know use this oil because it has the high zinc we need for flat tappet cams. I have a 1972 Plymouth Roadrunner with a 440 and so far no problems.

Bought the 3 gallon eco pack poured into jugs and only had 2 gallon and 3 quarts if they are all like this I'll not be buying anymore!!!!!!!!!!!

Been using in my tractor trailers for over 40 years and over 5 million miles. Never had an oil related failure. There are newer and more expensive oils o in t there, but it’s hard to argue with success…

Wouldn’t wanna run anything else in my truck, others oils don’t last and make the truck run a little funky. 1996 7.3

I have been using Rotella T ever since I bought my Dodge RAM diesel in 2006. The truck is used on the ranch and often on rugged terrain. For years commuted from Houston every weekend so lots of highway driving. Exceptional oil for my Cummins diesel.

My 1979 Volvo 244 DL with 231000 km has been treated to Shell Rotella T4 10W30 since Sept. 7, 2019, odometer at 215477. The overhead cam/valve sound is quieter at 3000 R.P.M. on the 400 series highways at 100 km/h. The rear crankshaft oil seal has stopped seeping oil this year. I used to use synthetic oil. I can experience that Shell Rotella T4 10W30 oil really agrees with the 2.1 L, B21 A naturally aspirated gasoline engine. These are long-lived engines, and anything I can do to prolong its life is appreciated. Thanks, Shell engineers, for the extra protection of Z.D.D.P. for the camshaft lobes!

Who picked the 2.5 gallon container size... obviously they don’t change their own oil. My truck requires 13 quarts... normally 3 gallons and 1 quart. Stupid

I use this twice a year changing out all my motorcycles oil. Never had a problem, last as long if not longer then the more expensive motorcycle oils for tappets. I can tell I need a change when the gear dogs click louder than normal. I get about 2500 miles out of a change in my old air cooled shared sump bikes. I'm sure I could go longer, oil still looks nice when I drain it. I just prefer to change it at manufacturer intervals. I then use the used oil in my mowers for a half season of more. Have one mower that's been going strong for 11 years, still doesn't smoke and starts every time. Wouldn't trust anything else in my old fleet of tappet head bikes.

I live in Canada and store my oil in an unheated shop. Twice I have cracked open a new 5 gal oil pale, dumped it into an engine and had table spoon sized ice chunks come out. The oil is good quality but the pales allow moisture to get in. Use a screen.

I bought this truck almost 5 years ago it had 85,000 miles on it when I bought it it now has 123,000 and I have been using Rotella 15/40 - T-4 and have always change my oil at around 5,000 miles and i see most people don’t change their oil until 7,500 or more it’s been awesome I love the oil and the protection that it has, But I have got a question about the T-5 will it harm my engine if I wanna switch to synthetic T-5 or would I be better off staying with T-4 ?????

Even in gasoline engines, this stuff is great! The zinc conditions the aluminum head and the cleaning agents are great in high mileage engines too!

I've used T4 in all my diesel construction for over 20 years. Never a failure to stand -up to the demands we put on it.

I've used Rotella T4 15-40 in my 1300cc liquid cooled motorcycle for years because of its heat hadling capabilities and wear resistance. Very pleased with the results and does not compromise the clutch action.

It was great and met my expectations and it was also great to find it at very great price. It beat everyone else by far. Go Home Depot.

I have been running Rotella 15W-40 in my Mercedes 300 Turbodiesel for years. Unlike what the instructions say about a 5,000mi oil change, I change my oil every 3,000mi. The car now has 528,000mi on it without overhaul yet! I also use Rotella 15W-40 in a pickup with a 454 engine pulling a 11,000lb chorus trailer.

A solid performer for my diesel truck. I use it all the time

I've used RotellaT4 in my 2002Chevy 2500HD Duramax from the first oil change and every 5000 ml. sense.

I've been using Rotella T4 for a long time in my semi truck engine. Newer had any problems. When you change the oil in the engine you can tell that it's Rotella, because it has specific scent no other oil has. Great product.

I use 27 quarts to change the oil in my motor home and has never let me down. Great product

Ever since purchasing my truck only oil I will use in my diesel.

The only oil I use in my diesel truck and tractor.

This is the only oil I have run in my 2001 Ford F-250 Superduty 7.3 diesel. I now have 248K miles on it and it runs like it was new. I would never try any other oil..

I've been using shell rotella since i bought my first 18Wheeler,i have never been down due to oil issues,"rotella is my brand !!"

I was concerned when I heard shell discontinued production of Triple Protection Rotella. This is my second oil change with this oil and I run it for 5000-7000 miles. UOA show great additive packs and the wear metals in my samples have decreased since the change to T4. Great oil and a great company. I've been using Rotella since the Rotella-T days.

I have over 150 thousand miles on my 5.9 Cummins. with nothing but Rotella for my engine oil. Great protection

I have been using Shell Rotella 15w-40 for my diesels for about 10 years now, and I am very satisfied with the performance of this oil. I have had no problems with it at all!

I've been changing oil every 5000 miles using Shell Rotella since 2000 in my Ford 7.3 diesel and am very satisfied with this oil. Have not had any oil related problems what ever. Pulled bumper and 5th wheel trailers through Colorado mountains: a horse trailer up steep rocky roads in Missouri. This truck is used hard, Rotella is my oil.

Although this product has many modern applications, I use Rotella 15W-40 and 10W-30 in all my antique tractors that call for 30 and 40 weight oil. It's much better than what they've been run on for the bulk of their life and has no doubt extended the lives of their old engines.
