Engine oil Shell or Lucas

I was running Motul 8100 and got tired of having to pay alot of money and get it shipped, so I did alot of research and found that overall, the Rotella is one of the best oils for the price, so I switched to that. I notice no difference in power, and it costs alot less

And I use a 15W40 diesel oil year round here in the Bay Area, currently Rotella-T, but have used Mobil Delvac 1300, Delo and others.

i always used 15w40. usually shell rotella in all my old diesels. sometimes i used castrol. but it was always 15w40

Rotella T 5/40 syn hopefully going in this weekend after a seafoam treatment. 25 CAD for 4 litres, inexpensive as it gets up here and you can get it at any TSC or truckstop.

Personally I would run a higher detergent 40 weight oil such as Rotella synthetic 5W40 than a "high mileage" oil.

Rotella 5w40 here. IMO, I wouldn't run less than a 40w on the upper end if you do a lot of freeway driving.

I just changed my oil to Rotella T 5w40 Synthetic. It's great stuff. So far so good and the car runs smooth.

I use Lucas oil in my motor oil for 1990 VW 1.6L Jetta diesel. I started using Lucas Oil because a relative of mine has been driving a large semi for almost 30 years, and he, like many in the trucking industry, swear by Lucas Oil. Judging by the parts per million of metal present in my motor oil, my motor oil with 1 cup of Lucas Oil, was wearing pretty well.

I ended up buying the rotella t 5w40 stuff in the blue jug for like 16 bucks a gallon, my vr runs better and seams to like the stuff.

I am using Rotella T 5W 40 in my 1.6NA diesel and in my TDI. I have noticed no bad effects. The oil consumption is nil and there are no leaks, etc.
