Originally Posted By: CATERHAM I'd be interested to see a UOA on this oil to how well it stands up. My guess is pretty well. It has done an outstanding job for my application. I have a 2007 Porsche Cayman S that sees considerable track use in the warmer months, and is stored winters. My UOAs...

It is too bad HM couldn't help the leaks, but I think they're beyond the help of what oil can do. Still, it's worth a try in your motor.

The next stop was IKEA, so we compromised on the oil browsing

Two reasons for the short OCI (1) I've owned this car less than a year and believe the previous owner probably went over 15k for OCIs, and (2) the weather is getting colder, so I took advantage of a recent warm weekend to change the oil. I'm using HM in the warmer months to see if it helps my...

Below is my third UOA for this vehicle; the second with M1 10w40 HM. The first was with SM, this is SN. The ad-packs differ slightly, but the results were the same. Good wear numbers and it was still a 40-weight when removed. Nothing too exciting here, but it's another data point. I refilled...

This is the first UOA on my wife's PD-TDI Jetta. The vehicle now has 80k on it, but we got a complete new cylinder head installed at 65k due to a faulty injector seal that damaged the injector bore in the head (under CPO, lucky us). Given that only the valvetrain is newer, I don't think this...

While in Toronto this summer, celebrating our anniversary, my wife and I stopped at a Canadian Tire on the way home so I could browse oil. I picked up a 5L jug of Shell Rotella T5 Arctic Blend 0w40 (CF / CF-4 / SJ). Below is the VOA: (ALL Values not listed are equal to 0 ppm) Potassium - 3...

Believe it or not, I can pick up the 5w50 from PetroAlliance for about what 0w40 costs at Walmart. I've used 0w40 at the track, and subjectively (less smoke under track conditions, less oil consumption), I prefer the 5w50. I plan to run this OCI for the entire track season next year, which I...

I heard back from Shell Technical US; they recommended using the T5 0w40 blend and then filling with T6 5w40 until full. I could just use the T6, but I bought the T5 0w40 in Canada (for $40 CDN, gulp) and I want to use it in something. It's not suited for my wife's PD-TDI or my Cayman S motor...

UPDATE Thanks for all of the interesting feedback. You guys need to relax; the BMW cost me $4,500 last winter. If my 2.5L blows up, that means I get to put a 3.0L M54 in it At any rate, I drained the Mobil 5w50 from the Porsche and sent in a sample. Unfortunately, I was in a hurry and didn't...

My 2007 Cayman S sees quite a bit of track-time at Mid-Ohio Sports Car Course. I typically run in the advanced or intermediate run group, so the car is driven pretty hard. This OCI saw 4,100 total miles, with about 500 of those miles being driven on the track. I stretched the OCI to three total...

I recently picked up four cases of M1 5w50 for the wholesale distributor near my work (Petroalliance / Cleveland). All four cases were API SN, so I sent in a sample to see what (if anything) changed in this formulation. Good news -- Not much changed! Below is a link to a VOA I had done with API...

BITOG'ers -- please reply to this ONLY if you have constructive advise...don't waste your time telling me you wouldn't recommend this...cause I'm doing it anyway ;-) I have a 2002 BMW 525iT with the 2.5L M54 wagon. After a short trip to Toronto this summer, I also have one 5L jug of Shell...

I also took advantage of the local wholesaler in Cleveland (PetroAlliance) and replenished my supply of M1 5w50 for my Porsche Cayman S. It sees pretty regular track use at Mid-Ohio in the summer, so I wanted a Porsche A40 approved 50 weight oil...which M1 5w50 is. Anyway, I got 4 cases...
