quieter valve train, end seal oil seepage abated

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!

Good stuff

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.

SHELL IS BEING SNEAKY AND CHEATING CUSTOMERS

We have exclusively used Rotella Oil in our heavy duty commercial trucks for over 35 years and been very happy with the quality of the oil. It has served our vehicles well. Here is our gripe.... SHELL OIL COMPANY HAS STOPPED FILLING UP THE GALLON CONTAINERS WITH OIL AND SHORTING US AT LEAST A QUART OR MORE OUT OF EVERY GALLON WE PURCHASE SO WE ARE NOT GETTING A FULL GALLON AS CLEARLY STATED ON THE OUTSIDE OF THE CONTAINER. THIS PRACTICE IS DISHONEST SHELL!!! Go ahead and open the top and look down into the container and you will see the oil is barely over the halfway mark of the gallon container.

Shell Rotella T 15W-40 Diesel motor oil

Use this in my '06 Duramax LBZ/ my air cooled 4 stroke engines(lawnmowers/generators), and all of my 4 stroke dirt bikes. Superior to any non-synthetic oil I have ever used. Recommended to all my friends/acquaintances.

KTM 300 Gearbox

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.

Excellent Motorcycle Oil

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.

Great oil

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.

Muscle Car Oil

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.

Great oil

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…
