We would like to address those specific questions that have been emailed to us.
DT40 or DI40 – which is correct for my Porsche engine?
-
If your Porsche is port injected, you can use Driven DT40 in place of a factory 0w40 or 5w40 A40 approved oil.
-
If direct injected and normally aspirated, technically you can run DT40, but you really should be using Driven DI40. We also recommend DI40 in place of any C40 oil.
- If direct fuel injected AND turbo or supercharged, you should not use DT40 – only use DI40. The reason for this is that LSPI, or low speed pre-ignition, can occur when calcium detergent levels are over 2000 ppm in a gasoline direct fuel injected engine under boost. DT40 and any A40 approved oil will have more than 2000 ppm of Ca, making those oils unsuitable for those engines.
My Porsche is under warranty. What should I be doing?
It’s best to use a factory approved oil if your Porsche is under warranty, but not all A40 oils perform the same. Two popular choices are Liquimoly and Motul. You might want to give those a try and cut your oil change intervals in half as a starting point. Once your Porsche is out of warranty, then you can use what oil is best for the engine, regardless of whether or not it carries factory approval.
When should I change my oil on my new Porsche?
Most experts recommend changing the oil at 1000 miles. If that’s not possible, simply changing the filter and topping off the oil is the single next best thing you can do.
Do I have to use a race oil for the track?
Although we do recommend using Driven XP race oils anytime you are tracking your Porsche, we know this isn’t always practical. Driven DI oils can be used in place of DT for newer watercooled models to provide even greater protection for your engine. Although it’s ideal to head to the track on fresh oil, if you don’t have time to change your oil before a track event, bare minimum change your oil filter and top off the oil with fresh oil.
What oil viscosity is correct for the track?
Flat 6 Innovations recommend using XP6 for both air-cooled and water-cooled Porsche models when heading to the track. This is especially important if you see oil temperatures sustained over 225F or 240F intermittently. High oil temperatures can exacerbate oil starvation issues on models known for oiling issues on track, even with a deep sump fitted.
Can I switch between oils safely? Do I need to use a flush oil when switching?
Although it’s ideal to use a flush oil of the same brand as what you are changing to, it’s not 100% necessary. Just know that if you do used oil analysis, that the next sample won’t give as good of results as the subsequent one. It is not necessary to use a flush oil when changing between different Driven products, even if going between a street and race oil or conventional and synthetic. The only time we do not recommend switching to a full synthetic from a conventional or semi-synthetic is if your engine has any oil leaks. Likewise, if your engine hasn’t been rebuilt and has always run a conventional oil, switching to a full synthetic may cause leaks.
