Engine oil Shell or OEM Subaru

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 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.

In my area, I always been able to find Shell Rotella T 5w40 synthetic motor oil. It's a Group III oil and is capable of 10K mile oil changes in the AHU/1Z/ALH TDI engines and should do fine for your TD.

I have used Rotella full synthetic 5w40 from day 1. No complaints. I work for an oil distribution company, and get to ask people questions that have been in the business before I was born. Eveyone of them says the same thing. Shell has forgotten more then the others will ever know.

Josh, just get yourself a gallon of Rotella syn 5W40 oil from Wallysmart. It's a perfect solution for an old buggy like yours. I think it's around $14/gallon and is ideal for year round use. you may even pickup a couple of MPG.
