Driven Racing Oil DT40 High Zinc Synthetic Oil 5w-40 Motor Oil (1 Quart), 02406

Independently recommended for my Porsche to help minimize bore scoring- I just hit 80,000 miles and received oil analysis results - all green/ good granted that history is with Mobil 1 but as a bit of a comfort level I plan to use Driven moving forward

Preventative measure to avoid cylinder scoring and IMS bearing failure.

Only oil I use in Porsche Boxster due to IMS bearing failures

This is a GREAT product for all M96/97 engine owners, my car starts with less noise and I have ZERO consumption. I migrated off of the factory Mobil1 0w40 to Motul. Then I bought this. I will always buy this as it is cheap insurance for a motor that is extremely expensive to rebuild, and I know.. I spent 18K on getting mine overhauled when my IMS bearing let loose.

This oil has been used in my engine (3.8l Porsche flat-six) since it was rebuilt. It's been over a year and a half with lots of track miles and no sign of wear and no oil consumption.

This oil was recommended to me by the Mechanic I trusted to swap out my IMS bearing in my 996. I am normlly and AMSOIL fan, however this is also synthetic. I have only had one oil change on it, but the oil looked great, if the car were not a Porsche I probably would not have changed it.

The only engine oil I use in my cayman 987S and on my Audi B5 S4

Great oil, use it in my built audi!!
