Meets the Specifications for VW TDI
Size: 1 Quart Pack of 6
I don’t get too excited about motor oil; it just needs to meet the specifications for the application. This oil meets the standards for VW TDI engines (VW 504.00 & 507.00) and several other European turbo diesel engines. While this type of oil is locally available, it is very costly if purchased locally by the quart. There are plenty of other brands like Liqui Moly and Mobile One that offer oils which will meet the specifications, so pick the one you like. After some research, I found there are no great deals in terms of cost, all of the oils that meet the VW 504.00 & 507.00 specifications are going to be on the expensive side. However, Castrol is the brand used by VW, so if that’s important to you, there’s your option. I have used this type of oil for several years and many thousands of miles with zero issues. If you do your own maintenance, you might as well save a little money and buy in bulk. Storage and shelf life of motor oil is not a concern.

Great oil for BMWs
Size: 1 Quart Pack of 6
Not much too say, it's the classic oil, only thing I can note is that it came with the old packaging and all that, but it works great for my car and runs smooth and without noises or temps, good value, and fairly fast shipping, good thing I can find it on here because none of my local auto stores had it on stock.
