Hi,

What do you think about the power gains/variances due to oil grade or oil brand ? In this video they did 10 runs, 5 with Mobil 1 5w-30 and 5 with Motul 300v 5w-30 and they say the gained 16hp on average. The power levels are very comparable between that Camaro and a tuned N54. Also, the N54 could benefit more because it (probably) has a higher redline than the Camaro engine.

send it to mythbusters

lol.. dont think so

[zerep1]

the only thing that really matters is weight when your comparing the approved oils and i really do think that a thicker oil would be better for the 335i i mean have you seen how the stock oil comes out "like water"

[Lulz_M3]

Engines now-a-days are built using extremely tight tolerances, thin oil is a must for proper lubrication. Changing to a thicker oil would be ill advised.

It has been proven on other cars as well... Motul oils do help you put down a little bit more power but at the expense of a little more wear and tear on the engine.

i understand that but with the temps the 335i runs do you think the the stock oil is acceptable at 150whp over stock

[Lulz_M3]

Yes, DME failsafes are in place to protect the engine. It seems the N54 has a target window it likes to operate in as far as engine and oil temperatures, after that the Nannies put you in time out.

This is false. You think Motul is hard on engines? Wow...

Hi all,

it is 6 months since I turned from Castrol Edge Sport 0W40 to Motul 300V 5W30.

All I can say, the first time I started the car the engine ran a lot smoother. On soft acceleration I could swear that the engine revved up smoother and without any hesitation.

I don't know if I gained any HP, it is difficult to understand it with a 400++ car. Nevertheless, my friend with his 135 said the very same thing. I was really afraid announcing that, but it's a fact.

Don't expect to lower your 0-60 time. If you try this, you will understand it yourself.

PS. My rear turbo was burning some oil. I ended up adding 1 liter ;every 1500 km or so. After switching to 300V I didn't add a drop of oil. Maybe this has to do that Motul is fully synthetic. Though, my Synapse BOV spits more oil during blow off (and looks like that OCC is mandatory)

Same here. I switched after seeing some great results with some of my clients exotic cars. It's tough to stomach the cost of it, but the Motul works quite well.

Add another one. I swear by Motul. My car is much happier with all of my fluids changed over to Motul stuff.

Which Motul fluids are you using specifically? Thanks.

[Doyle]

300v 10w40, multi ATF, 75w90 gear 300, mocool, and rbf600

lol almost everything they make!

Change engine oil every 5-7k, driveline at 50k, and coolant/brakes every track season.

Just curious, why did you go with 10W40 instead of 5W40 or 5W30?

Because this engine runs hot as hell! I would do 15w50 for the track, but I DD my car and didn't want to go that extreme. This was the solution my shop had. They ran it on their 335i for OLOA and they said it was key in keeping engine temps under control.

[JamesM3M5]

I've been using Motul oils in customer cars for years now. I have the regular 8100 X-cess 5W40 in my 335i for 7500 miles now (finally time for a change), and I have only added 0.5 liter the whole time. I drive relatively hard, ran several highway trips at 80+ MPH average speed, and 22 miles each day commute city driving.

I always recommend the 300V 10W40 for track BMWs, since it holds up to extreme temps (think inside the turbos) without coking or breakdown. We support several BMWCCA/NASA club racers, and all their motors all run with Motul 300V.

One quick anecdote - had a customer tracking his 335i, stock at the time, and he was faster than another 335i that same day. He had 300V 10W40 and never went to limp mode, while the other 335i with BMW oil (junk, IMHO) was hitting limp mode after 3-4 laps. This was not due to driver skill, our guy was faster and still didn't hit limp mode.

Nice info everyone, thanks ! I am thinking of changing the oil with Motul 300V 5w-30 or Castrol Edge 5w-30 (currently have Castrol Edge 0w-40) while on the dyno to see the difference. But to add the dyno cost to the already very high cost of the Motul 300v, is a little hard to swallow, I may only use the Virtual Dyno

I can swear that last year I got a power increase on the dyno when switching from Castrol Edge Sport 0w-40 to Castrol Edge 5w-30, but there were some other changes between the dynos - intake (shouldn't matter on the dyno), oil change and different gas (ignition advance was logged to be identical, so it shouldn't matter).

[enrita]

Fuchs 5W-40 Race is another great oil for the N54. Classed as the Motul V300.

[CSL335i]

Regarding the motor oils:

- I am also using Motul 300V Power 5W40 since the last 45k km for my n54 335i. Has very good experiences with that oil. Much less oil consumption then with Castrol during the frst 15K. I have also tried Motul 8100 X-Clean once, but oil consumptaion was higher then 300V.
- In my F10 M5 i will also switch to Motul 300V Power 5W40, once i reach my first oil change intervall, which i will have at 2.000km (currently I have 1.400 km in the clock)
- In my F20 116i, i will switch to either Motul 300 V Power 5W40 or Motul LL04 5W40 specific oil.
- In my F30 320d, i will switch to Motul LL04 5W40 specific oil. (Motul 300V is not recommended for diesel particular filter)
- In my e93 M3 i am using Castrol Edge 10W60, however i am thinking to try LIQUI-MOLY SYNTHOIL RACE TECH GT1 10W-60

Motul 300V is really takes the cakes, however we should consider, that we really have to take care of oil change intervall, when use Motul 300V Power. I am changing my oils first at 2.000Km, than at 10.000km and finally every 10K. 10K is the max, and depends on driving style, season conditions, etc.
I dont track my car, just sometimes hard street drive

I have heard good things as well about Fuchs Titan Race Pro S 5W-40 Ester Synthetic Engine Oil
