FREE WEBINAR: IMS Myths, Facts & Fixes.

Ask the Experts - Live!

 

Join Charles Navarro (LN Engineering), Jake Raby (IMS Solution Inventor), and Tony Callas (Callas Rennsport) on Wednesday, Aug 20th 2025 at 8PM Eastern Time for an exclusive live webinar on the Porsche M96/ M97 Intermediate Shaft (IMS) bearing. This is your chance to learn directly from the experts who’ve led the charge in IMS bearing diagnosis, repair and prevention with live Q&A- Bring your questions!

Whether you’re a Porsche owner, a shop tech, or just love engine tech, this session will cover real-world insights, failure modes, replacement options, and long-term solutions.

What is the best engine oil for my Porsche?

If you are receiving these emails, you probably already know why you should be using Driven DT40 or DI40. Just to touch upon something discussed in last month’s oil webinar, one thing you might not know, is if you have bore scoring, that it is important to switch up to Driven DT50, or preferably, DI50, to extend the life of your engine. The increased high temp-high sheer (HTHS) viscosity provides extra “cushion” between parts while still providing the much needed ZDDP and Moly.

What is the best engine oil for my Porsche?


Another thing you might not be aware of is that if you track your Porsche, even though an A40 oil might be adequate, using Driven’s DI oils on mixed street/track cars is a worthwhile upgrade, if you don’t want to go through the trouble of running a true race oil. If your oil temps are reaching 235-240F, it is equally important to consider moving to a 50wt, so either DI50 or Driven XP6, the latter being Driven’s true race oil. This holds true for most if not all Boxster, Cayman, and 911 models.

 

Pro tip: If you don’t have time to change your oil before a track day, which is preferred, simply changing your oil filter and topping off your oil with fresh oil is the next best thing. The added benefit of doing this is you can take the filter off immediately after the event and inspect it, and you’ll for sure know that if you find something, it wasn’t there before the track event.

Should I stick to OEM Oil Advice?

If you are car and oil geeks like us, you probably heard that GM recalled hundreds of thousands of trucks and SUVs with the 6.2 V8, with their fix being to change out 0w20 for 0w40. Along those same lines, another thing you might not be aware of is that many of the non-sports call models call for C20 or C30 oils, using lower viscosities for the purpose of improving fuel economy, just like the addition of start/stop, which is something most of us turn off immediately. For those models, we’ve seen significant improvement in wear reduction going to a C40, or once you are out of warranty, DI40. You might lose some fuel economy, but your engine will thank you!
