So... we've been approached by a Motul distributor about carrying the Motul product line. We already sell a lot of their brake fluids, but not much else. We're going to sign up with them, but I wanted to get the peanut gallery's opinion on Motul oils and lubricants. Do any of you use it? Would you? thoughts?

I figured we needed a new oil thread...it's been a while! lol

 

With the new Porsche C40 oilniw being required in all newer cars and the Mobil 1 C40 in short supply I have heard of several owners buying Motil 5W-40 for their vehicles. Seems like a good time to stock some.

 

For 944, I use BradPenn semi-synthetic 20W-50. BradPenn is the former name, not in the shop to provide new name. Lots of history, originally Kendall Oil

 

300v is an excellent track oil. 8100 is good street stuff. I don't have a car that particularly benefits from either and I run the driven xp6 in my track car, but i'd substitute for 300v in a pinch.

 

I've been running 300V for years in cars I track. Also running Motul 660 brake fluid in those cars, no issues.

 

Yes, I would buy it.
I use Motul or LiquiMolly, both great oils. As are the brands mentioned above.

 

I use Brembo HTC 64T brake fluid and Driven XP6 oil in my race car......

 

For the past three years I've had every oil change in my Spec Boxster tested by Blackstone, mostly because Im a nerd. I've run Mobil1 5-50, 15-50, Motul 8100 5-40, Motul 5-50 Sport, usually changing it after every 10 hours of track time. For the past two fills I used Motul 300V, first at 9 hours and then at 14 hours. The last sample at 14 had the lowest wear metals of any prior. What does that equate to when you're talking about parts per million? I have no idea but it cant be bad. It's more expensive then most offerings out there but it seams like I can run it at least 50% longer.

What gives me no joy is the trace amount of coolant in the oil. We'll see..

 

Motul motor oil has a good reputation, I know several people who swear by it. I've never used it, I use Driven oil in my 981. Motul's 8100 X-Cess 5w-40 carries the Porsche A40 approval and can be used in any Porsche specifying Mobil 1 0w-40.

 

What grade 300V are you using?

 

I've used Motul products for many years including in my race car. Good stuff.

 

Driven is good oil but they currently don't make a C40 spec. I received an email from them to this effect, so for warranty purposes it won't fly. Mobil 1, Mobil and Liqui Moly are only US options at present.

 

For those using or interested in using Motul oils...what grades are you using? i.e. what should we start stocking?

 

I've been using Motul X-cess 8100 5w40 in my 987 Cayman S race car for years, changing every 6-10 hours of usage. Have done a few blackstone samples, always come back very clean with good remarks from their lab. I tried Liqui Moly once, same 5w40 weight, and I had to add a liter at the track that weekend. With the Motul 5w40, I never (ever) have to add oil between the 6-10 hour change interval. Therefore it's Motul with no other consideration moving forward. I've considered the 300V but at double the price and the very good results I've had with the 8100, I see no need to change at this time.

 

Nick from Motul suggested a 55% of 0W40 and 45% of 20W60 to get to roughly 5W50 if that's where one wants to be but he disclaimed it was not a "formal recommendation". Might just try the 10-40 in the future but 50 makes me feel "safer" in the middle of the summer in my mind.

The below is a direct quote from him on Rennlist re: 300V intervals:
"For mixed driving (track and street), being more conservative will be a good practice- I'd recommend draining at 3,000 miles and see what the UOA looks like. The typical street-driving drain interval is ~3,000 miles and a 90% track and 10% street mix would be closer to 750 to 1,000 miles, depending on engine temps, length of sessions, etc."
