I have begun to notice that I am losing oil since I had my custom MHD tune. I have added 2 quarts in the past 5000 Km's. Now maybe with all the testing etc, this should be expected. Or maybe it is a byproduct of the tune?

I guess my question is, what oil should I be using with my custom Wedge MHD Tune?

[GripAndRip]

I haven't noticed major oil consumption yet. I'm still really early into my Wedge tune and haven't drove much as I am out of the country. However, several other members have noticed a major increase in oil consumption. I wonder if they can all be correlated to the Wedge tune.

[ANMVQ]

Me! My thread possible oil issue? I justed added 1 quart last weekend. I just had an oil change about a month ago and have never had to add oil before. I'm going to change to redline 5w30 and move away from th BMW oil. Makes sense that we are basically doubling the stock boost we'd seem some oil loss. Been running the custom tune about a month also

Same issue. I'm wondering if this is due to the higher water pump duty cycle that Ken uses to keep oil Temps cool. Wondering if that is slowing the oil heating process and therefore the oil is a lower viscosity longer. Just a guess.

[D's Bimmer]

Ken, can you chime in here? Maybe the solution is a slightly different oil variation? Any input would be appreciated.

Do you guys get visible exhaust on WOT? I notice is more now.

I dont see any oil burning at all. I switched to Liqui Moly 5W-40 and have gone about 300 (hard) miles, no loss on this oil yet.

Not sure how you would correlate added oil loss to a specific tune or tuner. The fact that you are demanding an extra 100 hp from the engine might have something to do with it, not to mention the increase of boost pressure. The temp drop on the oil due to the coolant system starting the ramp up duty cycle a bit quicker. Oil still runs at operational temperature, just a bit lower than normal.

Yeah I'm not trying to say it is specifically your tune or tuning style. I guess I should have said "the tune" to be more general. I was just suggesting that the recent oil consumption threads and the fact that all the authors have significantly increased the performance in their cars can be correlated. Any advice for those impacted on how to mitigate this possible side effect?

I was originally on 5w-30 and I'm on 40 now. I didn't see loss on 5w-30 and I just changed over yesterday to new oil.

Knock on wood, I have seen no significant increase in oil loss. However, I have seen a significant increase in my enjoyment and heart rate while driving

This is basically the same thing people were saying about burble. i also have no oil in the charge pipe but yet I go through a qt of oil every thousand miles. Also depends on how I'm driving the car. I wouldn't think anything of a qt of loss on a track day event. For this I do recommend a quality zddp oil and a 0-50 mobil 1 race has proven performance. It's expensive, but if you are abusing your car, paying a bit more to ensure proper lubrication is worth it considering an engine replacement could set you back 10k if you can't do they work yourself.

Engines use oil two ways: by burning it, or leaking it. Assuming it's not the latter, than I'm guessing that ppl with new tunes are just really flogging their cars with multiple pulls, causing increased pressure on seals, gaskets, and rings, which inevitably leads to increased consumption as some of the oil finds it's way in to the combustion chamber, especially at higher boost levels (I imagine JB 4 users would also experience the same thing?).

Try this: return to a stock map and try to drive like a normal human being for a few days. Guessing consumption should return to normal??

[ANMVQ]

So I'm down another 1.5 quarts today, taking the tune out and going the dealer.
Also not saying anything is wrong with the tune, just don't want the dealer to see it( I have warranty).

WedgePerformance let me know when you're back from Hawaii. I'd like to test revision 19.1 without the increased cooling duty cycle.

I sent him a log of some things I'm experiencing and the bounce back I got said he's not back till 4/3. I'm hoping I get a revision the beginning of next week.

BTW just order Red-line 5w30

[CantCatchMe]

Hmm, I had a little bit of oil burning quicker when I used BMW's 5w-30(Shell oil). Since switching to Liqui Moly 5w-40, I haven't seen it happen since and I'm using Ken's custom map. I'll be getting PS2 custom maps from him so we'll see if any other changes occur as I'll continue using my oil for the last 10k miles. I will send a sample on this next oil change to blackstone.

Does your car have a factory oil cooler? Most if not all 2011's dont and Ken increases the water pump duty cycle to provide additional oil cooling.

I'm xDrive which came with the 17" msport wheels. I don't have it on my 2012. I am going to get one at some point this summer. Ken did enable the increased water pump duty cycle which I like since my temps were at 250 and above on warm days. Now I never go past 220, but the need for oil cooler is a must sooner rather than later.

KEn and I had our turbos put on within a few weeks of each other, I 'think' I am at like 3k~ miles into mine. We both drive as hard when we drive our cars.

Ken's car eats up oil a little quicker than mine, starting 2 weeks ago, I went down to 3/4, last week 1/2, and yesterday I am at 1/4 on the reader.
I use liquid moly as well, 5-40. I guess this is normal since we've added nearly 150 whp and god knows how much more torque vs stock on our engines

Damn! Well hopefully I don't eat through oil like that otherwise I may try Joe Gibbs performance oil. I hear it's highly recommended by Pure.

[ANMVQ]

Thanx Rob for the input here,

I guess I'm an outlier then, as I do not drive hard at all (can't) traffic is slow durning the week and no room to do more than 70 MPH and if there is room it's only like 100 yards before traffic again and I'm not doing that to the car, When I'm not in traffic( wth the wife) running around on Saturdays I very really get to go WOT. I guess that's why I never saw or felt my rail crashing or the overboost issue till the week or so as I have had small windows to hit it and been getting tired of driving like grandma LOL. Been Jabbing it a little.

BTW I loved the fact that my oil temps were so low also on the tune, no back on my "Stock" PPK oil temps were back to just under 250 this morning on the way to work. Ken's tune they were mostly at 210-220

Do not have a factory oil cooler even tho I have the sport pack ;/

We'll see what happens when I get a revised tune this week and a switch to Red-line 5w30 next weekend.

Why do You want to test without the increased cooling duty cycle? Just curious.

[D's Bimmer]

I do notice visually that the exhaust is dark greyish on WOT. Like I am blowing oil out the exhaust. The back end of the car gets very dirty. Do others experience this?

Oil Smoke is generally blue in color, black is the fuel mixture being rich.
