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!

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!
