What do you think of this oil?

Hi everyone,

Im from the Land Down Under and was wondering what everyone thinks of this Australian branded 0w40 oil with PAO and Ester mixture?

It doesnt carry any BMW certifications if that is important to you.

Stout oil. I'd run it for non-extended drain intervals.

It carries the Porsche certification. It should be a good oil. High TBN as well.

Yeah totally. I just changed out my 5k kms (3K miles) old oil and oil filter that was changed at the dealership which was Genuine BMW M TwinPower 0w40 oil that they used.

First impressions I have felt is the engine idles and revs smoother and the turbos sound less whiney than before. Another significant difference is that the oil temp with the Penrite 0w40 never goes above 105 degrees Celsius in efficients and sports mode and that the oil heats up quicker than the BMW M TwinPower oil in the morning. Before on the M TwinPower oil, the oil would always get to around 110 degrees Celsius and takes about 2 mins longer to move up on the oil temp gauge. Also another key difference is that there is always a hill that I would need to drop to 3rd gear in efficient mode to climb, now with the New Penrite Oil, it can climb the hill in 4th gear in efficient mode. very interesting indeed...

I seriously doubt that you notice a difference. Theoretically a difference in oil viscosity might result in a quantifiable difference on friction of the different engine components but you are talking about oils with the same viscosity.

By the way your oil was not changed after 1200 miles/2000 kilometers? They should have changed the oil + filter, also changed rear diff + transmission (manual only) fluids.

Thats what I was thinking. Likely a placebo effect and not actually a quantifiable difference. It would have to be a pretty big viscosity change to notice a performance difference (like going from a 10w60 to a 0w20). I have used the BMW branded 0w30, 5w30, and Castrol 0w40 in my car and there is no difference in overall performance between them, aside from the 30wt oils reaching operating temp ever so slightly quicker.

Well just stating my observations, whether you believe I felt a difference or just feeling a placebo is entirely up to you.

And my M3 already has 53k kms on it (32k miles) as a 2016 F80 M3 LCI. Prior to my ownership, the previous owner changed the oil once a year or 15K kms with BMW M TwinPower each time at the dealership. The car had the first engine oil change and rear diff service at 2500kms. Also had the spark plugs and ignition coils replaced 5k kms ago by the dealer at its last service. I simply changed the oil that was changed at its last service 5k kms ago and can feel the difference. Wasn't instant in the difference (as noted in placebo effects) but after a few runs of the M3, can definitely feel an appreciable difference no doubt.

Seeing as you're from Florida which has similar summer weather to where I am from, do you find that the BMW branded 0w40 degrades quickly? I have timed the 5k kms old (3k miles old) BMW branded 0w40 warm up period on a 25 degree Celsius morning with same driving patterns and it takes 4 mins and 10 seconds to move from the 70 degrees Celsius mark. Whereas the new Penrite oil moves from the 70 in 2 mins and 45 seconds. Which is almost 2 mins faster. How do you explain that?

I haven't used the bmw branded 0w40 nor have I done any used oil analysis on my oil so I couldn't speak to how they do or do not degrade but I change my oil every 5k miles so it's not a concern for me.

As for your experience with the warm up time, it could variables in the ambient conditions or traffic conditions or it really could be the oil formulation which allows it to warm up faster. But either way I wouldn't consider a 1 minute difference in warm up time anything significant.

But hey crazier things have happened so if you notice some positive changes then stick with it!

Are you tuned? I have been tuned for the past 300 kms on the BM3 stage 1 91 octane because we have crappy fuel here in Australia and tuned with the BM3 M4 CS tune for the past 200 kms because I find the CS tune smoother and better linear delivery of torque

[gatorfast]

Im running the CS tune as well, I love it. I have had it for 15k+ miles now.

Does the CS tune void warranty with your BMW dealer? My dealer doesn't void warranty if its a CS tune because they say its a BMW calibrated tune and is BMW approved for the same platform of the M3 Non-ZCP seeing as they share the same hardware and components.

Its not something I have discussed with them and certainly wouldnt bring up voluntarily. I am hoping that I never have any major issues and therefore wont encounter any potential warranty concerns.

[G4BR13L]

They could void warranty but not for the complete car but unfortunately for the most important parts (engine, trandlission, diff, drivetrain, ...) so basically the entire powertrain.
