Yea, I pulled my oil filter cap out of curiosity to see 10w60 LM cold and it was really thick. I'm on redline 5w50 now from LM 10w60, which has lower viscosity at 40C and very close in viscosity at 100C with higher VI. I tried the 300v before and liked it but they don't recommend it on street cars and advise to change the oil after a track day. That would get pretty expensive since I try to drive the car a couple of times a week in the canyons and such.

I run it for two weekends, roughly 6 track days - Left 3 samples are Motul 300V 15w50, right 3 are Redline 50wt race.

Cool Experiment BBR, you ever think of trying 5w50?

Yes, that would seemingly be ideal, but Motul doesn't offer 5w50 in 300V, only in the Sport line. I still might go that way eventually.

Interestingly, though, the Motul 300v 15w50 Competition has a 40C viscosity value of 122 mm/s where the LiquiMoly 10w60 is a whopping 168 mm/s, making the LM much thicker for California "cold" starts, despite having a lower Winter rating.. Wish I had done more research on this years ago.

Dynotech which is Dyno Dynamics budget range I think.

Rebuilt S54 with the usual fixes in an e36 M3
Karbonius Airbox
Full Supersprint exhaust with ceramic coated stepped headers (no cats, resonators in mid pipes, race muffler)
Stock ECU with GreshM patch harness and HTE Performance Alpha N tune.
Bimmerworld twin fuel pump kit and rebuilt stock injectors
Australian 98ron fuel

Car made 295whp on a dyno where standard e46 M3s make around 250whp.
Green run is with a canned Alpha N tune, Red is HTE dyno tune.

What dyno is it that reads whp so much lower than others?

^^^Nice results, looks like some solid gains down low and up top.

^^^Real solid numbers for 91 octane! Was this on EAS’s dyno by any chance?

Yes this was at EAS

2005 M3 88k miles on 91 octane

CPI Headers

Ended up making 336whp and 261wtq. First run was stock tune. Tempted to go with the Karbonius airbox now.

Spent some time messing around on the dyno last weekend. I've been looking to switch oil since Liquimoly 10w60 hasn't been handling high oil temps well (and has a poor HTHS rating). I'm giving Motul 300v 15w50 a try, but figured why not change the oil on the dyno and see what happens? Motul claims a 7HP gain over their competitors using 300v on a Porsche Cup engine.

These runs were on a Dynapack hub dyno. These are amazing for tuning as there's almost no inertia so they show much more more detail in the torque/HP curves and eliminate variables like rolling friction or wheel/tire inertia. I know this particular Dynapack well as I've been tuning on it for about 10 years now, it reads close to Dynojet numbers, usually a few % lower depending on which Dynojet. Hoping to get on the local EAS Dynojet since that's where all the SoCal people seem to dyno. Theirs reads a bit high but at least it will be useful to compare to other cars.

Car really needs long tube headers and better cats, hoping I can pick up some decent power and smooth the torque curve a bit with some exhaust setup improvements in the future.

Now, of course this engine oil dyno test is not a completely fair comparison, but I did my best to control what variables I could as far as engine and dyno room temps (essentially identical between runs). However, the LM oil had about 1500 miles on it, and the Motul oil was brand new. They are also different rated viscosities. Interestingly, though, after almost any use, the LM shears down to the same viscosity as what Motul claim their 300v 15w50 is when new. It will be interesting to compare both used oil analyses once I put some time on this stuff. Anyway, for the results, 4.5HP and 2 ft-lb, nothing to write home about but still interesting.

More runs/info and dyno run video below. Ended up at 357whp on E67. One day I'd really like to see 375whp! I think it will be just barely possible with the right exhaust setup.

Liquimoly 10w60 vs Motul 300v competition 15w50:




91 octane vs E67 (67% Ethanol). Was hoping to get full E85 but didn't drain the tank enough and the local pump seems to be about E75 lately anyway for whatever reason. Gains are about what I'd expect, should be 15-17whp gain if I had full E85.




After some further tuning from E67 I got a few more HP and a bit more smoothing.

Stan,

If may I withdraw my friendly humor I guess you did not accept it. It wasn't in a negative
way at all. I do apologize. 🙏

You mentioned drunk on vapors ? Yes I am drunk most of the time and thank you for
noticing that one. I was giving some hints but they were not understood ehh.

Lol, you’re fine dude, I’m not mad...just didn’t understand your response. Think you misunderstood my attempt at a humorous retort as well. Plz explain exactly what you’re hinting at...inquiring minds want to know!

PM sent!

[Anri]

and the engine pulls strong.

Hi,

As long as you are happy how the engine pulls is all it matters !!!

Dude, I like you, but WTAF are you talking about!? Are you drunk typing again? Maybe YOU ARE breathing in too many VP vapors? I have misfires? We’re talking about ‘duracellttu’s car—right? So confused right now.

Anyway, the reason I suggested that he might be having a timing issue...is that power seems to peak around 7,500, which seems on the low side for cams/port work.

EDIT: ...and only my sexy time friends get to call me “stashy stash” btw.
