I sat in on this set of presentations last weekend..and blew my mind.

He also does one on ethanol, and there was _very little good news_, other than Top Tier fuels always, and then every 3mo use this:

Why marine?

It has a much higher concentration of (PEA I think) because marine environments have more moisture in the ethanal fuel..more doesn't hurt! Use it more often if not using Top Tier fuels.

Lake Speed Jr no longer works for Driven, he has his own Oil Analysis company now

Some oil analysis videos here too.
Also, wean the fuel system off ethanol, a huge dump of E free fuel, causes phase separation, where the ethanol and water in suspension will separate. Suggestion was 1/3 of a tank at a time..

Have not watched the video yet, but looked at the additive. I have had such a struggle with this issue, so I will be trying this. This 'saving the world' stuff is hard!

I thought it was gonna a bit of a goraner, but I learned a lot about oil.

The Forgotten On

I use BG44k every once in a while and it has always worked great in my 928s and my dad's 944.

It is definitely stronger than Techron, but it is more of a fuel system cleaner and that is more of a fuel system stabilizer with cleaning capabilities from what I can glean from the packaging.

Also, I forgot to mention that his Ethanol master class..is NOT in this video, but I did sit through it last Saturday as well.

Here _IT_ is....I found it. It is slightly dated, much more info is in his current presentation.

I've been using the Driven line of lubricants since taking a 997 engine building class with Jake Raby, Charles Navarro, Tony Callas, and Lake Speed, when he was still with Driven. Nothing performs as well in any of my engines as the proper Driven lubricant for that application and I've been promoting it here and on other Rennlist forums and Facebook since then. I do a UOA report on every oil change on every engine and have my own quantitative data to back up these statements. Every car I've bought where the PO was using something else, the Driven outperformed it in the first oil change and continued to improve for the next 2-3 before stabilizing at the new lower numbers.


I'm talking about besting the Shell Rotella and Valvoline VR1 that's very popular for our 928s and other classic Porsches. If you want to see the actual data, here it is.

Supercharged 928 where the original sample was Shell Rotalla and the subsequent ones are Driven DT50 15w50. Look at the metal wear differences! (last analysis is where I blew the head gasket and why coolant is present). She got a new engine after that but doesn't have the history of the previous motor since the torque tube needs to be redone and why I posted the older series.





'84 Euro S where PO also used Shell Rotella. This car is my regular use vehicle when not driving the pickup and sees about 5k miles/year. Again, look at the metal wear differences and even though the Rotella has a higher viscosity, that doesn't translate to protecting the engine as well. The moly content of the Driven oil as a friction reducer is one of the key elements that yields such good results that no one else uses. LM sells MoS2 and Ceratec as additives whereas Driven makes it part of the normal oil forumulation.




And for all the VR1 fans out there, here's the report from our recently acquired 944 S2 that the PO had been using VR1 in for the last 12 years while he owned it so that's the first analysis and DT50 in the latest one. This is my son's daily driver and will see about 10k miles a year as he drives it 5-6 times a day with school, soccer, guitar, dates, dinner pick-up etc. Metal wear #s at of well below the VR1 even with 1,500 additional miles of use on the Driven sample.




For anyone that wants a Mobil 1 comparison, here's my DFI Cayenne Turbo that came with Porsche filled Mobil 1 Euro Formula 0w40 from it's last dealer service. I switched it to Driven DT40 5w40 for all the other changes shown here. On the last service, I've switched it to Driven DI40 0w40 (that they're actually relabelling as a 5w40 now) because it is specifically formulated for DFI engines to prevent the LSPI that this injection methodology contributes to and because the DI40 is less fuel absorbent, which DFI also tends to contribute to the oil, but the DT40 worked great so I'm interested to see the analysis next year when I have the first DI40 sample analyzed.

Look at the Iron & Copper again






I also use Driven Carb Defender in every tank of fuel to counteract the effects o Ethanol and as a fuel stabilizer since some of these cars may take a few months to get through an entire tank.

My 84 Euro S has their AT3 transmission fluid in the trans and torque converter - shift smoothness was noticeably improved and their 75/90 gear oil in rear gearbox. My Cayenne has their 75/90 gear oil in the front and rear differentials and transfer case and the Z06 trans in the Spyder has their fluids in the trans and differential as well.

Thanks for sharing … that oil video was super informative.
