Bummer
After selling our 2000 Golf TDI and buying a '13 JSW last summer I decided to use the Formula M because the oil I was using in the old 1.9L was not okay for the 2.0L.
Based on my own bias, knowledge, and research that included a member here having driven about 150k [my memory], the Formula M seemed like a great though expensive, premium choice for my application and use. I purchased enough 6-packs from Amazon to cover the first few oil changes, and now need to decide if I should stock-up to take the car further, or just deal with the inevitable and find a new product.
Interesting timing of my [late] discovery that Formula M 5w-40 has been discontinued… I was actually thinking about researching if this very low ash oil would possibly be a good choice for my ’14 Ram/Cummins… Probably not regardless, and it looks like I’ll just stick with Delo 400 for the truck, a good, easy, and inexpensive choice.
