redline oil help pick 5w30 or 5w40

[joe916]

going to be doing my first oil change on my 14 audi q5 3.0T wanted to get some reviews and feedback on redline oil and who is using 5w30 or 5w40 thank you

[Phil Dammit]

Been using 5w30 castrol on mine for the last 12k miles. Mid atlantic weather.

Not a fan of Castrol I only used redline in my past cars but wanted some feedback on the 3.0T platform

Redline oil in does not meet Audi standards

If you are not a Castrol fan here you have a great choice but not redline

Redline meets the 502 and 507 amsoil and redline are the 2 best oil on the market doesn't mean they have to be on that list

Do you know the difference between the recommendation and approved for .........

Amsoil and redline are the 2 best oil on the market ? You have some evidence for this ???


After all, feel free to use the oil you want this is your choice and your right, but do not write that some oil is best on the market without solid evidence

FYI: VW 502.00 ( 2006 year ) and 507.00 (for diesel with DPF) standards are old, the newest are VW 508.00 / 509.00

5w40

[elijahallen]

I used 5-40, I will be sending in a sample to blackstone for a comparison to other oils I have tried but now with the additives its a whole new game. Any synthetic oil is good and the motor will be happy, when people argue about one or another I just laugh because I have tested most of them with Blackstone labs and there is zero difference in wear on the motor under normal driving conditions. My most recent oil sample had a weekend of track time so I will be curious to see how that compares but with past cars there was little to no more wear under those conditions as well.

Forgot to ask you are you using the redline Euro spec 5w40 or regular 5w40

5w40

Eurospec redline 5w40 or reg 5w40 how are your results?

Regular redline

Sent from my SM-G970U1 using Tapatalk

had any samples sent? any oil consumption? what is your driving type?

[MSq5]

Castrol Edge and Mobil 1 European formula are Audi approved synthetics. I know of no oil-related engine failures from using either of these. I'm content to run Mobile 1 0w40 European Car formula. Widely available and absolutely no oil consumption issues or other problems. I seriously doubt that Redline (which I use some of their other products) actually has a "better" engine oil for our cars.

[no thx]

Between Euro and regular I've read regular is a much better formulation for wear and performance compared to the approved. You can run t6 with no issues too. Since OP asked between the two I'd say 5w40 non euro . If he wanted an vw spec oil he can get one .

Its like comparing car coatings these days, they are all great, we don't drive cars with 12K redlines and we change our oil every 5-6K so oil never gets old and broken down. Silly topic IMHO.

“I’ve read . . . “. Proof, please. VW/Audi/Porche engineers with their engine wear testing standards might know a bit more than “I’ve read.”

I specifically asked about redline but everybody here changes the subject and everybody on here seems to think that Castrol or Mobil is only way to go lol

Quit confusing things were talking specifically about redline oil they have 2 options Euro spec and regular I never asked about Castrol or Mobil

Sorry, Joe. I wouldn’t want to confuse you with the facts. If it is not approved and certified as VW spec and so labeled on the bottle, many of us think that it matters. If you are looking for experience in using Redline in this engine, you may not get very many replies for that reason. Racing experience does not really transfer, as race engines are set up with much different internal bearing and piston specs for oil clearances, and those oils do not have detergent and other additives to allow for long oil change intervals. Race oil is much different.

Redline’s website says that approval letters are available proving that its Euro formula meets current VW specs. That helps, if true. But, it ought to be on the bottle. If so and insistent on Redline, use the Euro formula.

If your question assumes that it is equivalent, whether the certification is on the container, and you are deciding on viscosity, the answer may depend on where you live. 5w40 might be a better choice in hot weather like the Deep South where I live, or if the engine has some miles on it, and 5w30 might be better in cooler climates. The difference is slight, but might matter in 95-100+ degree temps.

i guess i was right amsoil and redline are the top 2 on that guys test results i just watched his video and the testing is really interesting but regarding motorsports redline is really big in NHRA pretty much every team uses redline for top fuel and redline is really big in motorcycle racing am not sure were you live because here in usa redline is well respected in racing and if you need more in dept proof bobistheoilguy.com will back up redline results

[userbbc]

I used to use redline and motul to potentially keep valve deposits at bay due to the ester content and potential blow back to clean the tops of the valves (as well as resistance to shearing.)

redline - went with 0w40 as redline 5w40 is a pretty heavy weight 5w40

overall - seat of pants impression was a smoother running engine and decent power throughout the life of the oil when using redline. did tend to feel some power discrepancy towards the end of oil life using motul.

only used dipstick extraction oil changes so not quite sure if this was causing the excess iron readings. overall, nothing too spectacular other than the seat of pants feel. Wasn't sure how to reach the valves with the supercharger in the way (used to be pretty easy with a boroscope on the 2.0t) so never saw whether valve deposits were actually reduced.

no problem. Of note - the previous UOA's were for the b8.5 3.0t q5 engine (font and type seem a bit off because opening the pdf up for editing on linux throws things off a bit)

however, this thread made me look back at the iron levels in my previous oil changes which generally hovered around average iron levels (all done through oil extraction - though at this point, i just extract directly into empty windshield washer fluid bottles via a $6 fluid transfer hand pump instead of the mityvac)

That being said, I only have one UOA of dealer changed oil. It's after the first oil change on the b9 sq5 at around 10k mi. with OEM Castrol. At 18k the iron levels actually a bit worse than average so I'm thinking the oil extraction method wasn't necessarily the reason for "only" average iron levels.

It is interesting to see Castrol stay pretty much in spec with respect to viscosity though. Or could be lighter weight oil doesn't shear as much during use?

OEM Castrol in the B9 SQ is 0w20?

Yes, exactly because it meets the Audi / VW standard 508/509

FYI, for those doing self-changing of their oil, regardless of brand and viscosity, be sure to buy a new washer. I learned the hard way that trying to reuse the old one is a big mistake. The leak was horrendous and quite a mess to clean up the undertray. It is very slow and will not show up on the floor until the undertray is full and you get a low oil warning on MMI. You can reuse the plug, but not the washer.

Or, use a vacuum extractor dipstick pump, as I do now.

And quality of the filter is as important, maybe more so than differences in VW 508/509 spec oil. Mann is extremely high quality and can be bought in bulk through Amazon.

My question has more to do with why OEM oil in the B9 turbo engine has lower viscosity than what is recommended for the B8-B8.5 supercharged engine. I worry about long term use of oils that light in hot climates and inside the turbocharger.

If the low viscosity is due to tighter internal engine clearances for emission control, that may not bode well for long engine life, especially in a turbo engine. Some engines cannot run 40w oils because of very small internal oil passageways that might allow oil to pool up in the valve covers, for instance, slow to drain back to be picked up by the oil pump, and starve the main bearings. Certain Ford V8 engines come to mind. But, if it’s just for emission standards, it might be better to run a heavier oil. Temps can reach almost 1500 F. in the turbo center shaft. Thin oil there seems like an invitation to early failure.

I wonder if the lighter oil (less friction) is just to meet overall fleet mileage per gallon goals at the expense of reliability.

Again you're spreading misinformation without actually knowing the group levels of oil redline oil and amsoil is a group v oil the Castrol you're mentioning is a lower-quality oil please do some research and red line oil carries racing spec and Street spec same with amsoil I'm guessing you don't have those oils in your country that's why you haven't heard of them

Amsoil and redline is a group v oil if you could get your hands on it that's the best oil you can buy make sure you use a high quality oil filter like Mann that 504-507 approval is bullshit you wonder why castrol is right on our oil cap go figure Castro pays a good amount of money for that

I just bought a fumoto LC-10sx with the clip going to install it I'll let you know how it goes had it on all my other previous cars oil changes are a breeze with it plus we have our oil filter on top so even easier going to make a square door on the oil pan cover so that way I won't have to take it on and off 😁

This same Castrol 0W-20 oil is also used by other manufacturers, for example Volvo for 2.0 engine 320HP ( turbo and compressor )

It has its own standards, not an American standard
