605 owners, what oil are you using?

[Gaki]

Just curious. Is it recommended to step to a heavier weight like a 20w 50 or should I just stick to what's on the approved vw/audi 502 list?

[c0rrup]

I usually used 5w40 but this time used 10w40 as the word going around lately is heavier oil will help journal bearing turbos, so why not? :)

[Ultrasport05]

I just asked the same question not that long ago

[dannyn424]

apparently it matters what exact oil you are comparing.....as different brands and then specific lines, have different addpacks... but my pics would be T6 5 w40 and liquimoly full synthetic 5w40 and 10w40..., mobil 1 full synthetic HM 10w40.... and I always wanted to try lubromoly 10w60 full synthetic.......(popular with BMWs) and I hear good things about Pennzoil full synthetic 5w40 too.....

[NOTORIOUS VR]

I ran Liqui Molly 5w-40 with great results from Blackstone. I wouldn't hesitate to tun T6 or GC either. But LM was my goto oil of choice.

I wouldn't go much thicker than that, all this thick oil is better talk is a bunch of BS.

T6 FTW!

The warranty on the RS6/K24 hybrids that SRM sells requires 20w50, so you may want to step up the weight a bit. Definitely would avoid oils like Mobil 1 0w40 that shear quickly.

If you really want good high weight oil, I would pick up Shell Helix Ultra 20w50 (factory fill on Ferrari's Challenge cars) or the OEM BMW M 10w60 stuff.

That's the stupidest thing I've ever heard... who the hell picks oil based on what turbos you have.

I'd love to see the testing that SRM did to come up with that nonsense. There's many other factors to think about when increasing the viscosity of the oil FWIW.

If this is actually the case then I'm boned if anything happens because this was written nowhere or ever communicated. The only thing that SRM/Sean ever said was he wouldn't warranty the turbos if I didn't have proof that they were primed using the priming plug on the front of the block.. So I snapped some pictures of priming via the priming plug and also performed the standard priming procedure prior to startup.

VR is correct

oil viscosity should be determined by the engine builder.

From their website:

THIS PRODUCT IS FOR OFF ROAD USE ONLY. One year LIMITED warranty. New Oil feed lines must be used. 20w-50 or heavier fully synthetic oil must be used with a high zinc content(warranty void with anything less) Work must be performed by a professional, certified mechanic. Warranty may be refused at seller's discretion if upon inspection, failure is the result of improper installation, overspeeding and/or oil starvation. All turbos are inspected, pressure tested and deemed working correctly prior to shipping.

^ That content has been updated since mid March when I purchased them, unfortunately I can't find a snapshot newer than Oct 2012. I'm not sure if it was during or after the site redesign though, which I may have just glossed over the new description since I had Sean invoice me. Not that I'm having any issues.. My understanding was the issue that was occurring was primarily due to poor priming techniques.

TBH, I don't believe the site even mentioned warranty when I purchased. The only mention was from Sean via email that he can't honor any warranty if I don't have proof the turbos were primed properly. Obviously that doesn't really help me in the event of failure either, just my experience.

I'm still going to run T6, not that there's any point in switching now, but even if there was I'd have to question why the hell I need to run 20w50 on a stock block in my climate and usage lol.

Old bump:

Contacted Tial and they also recommended 20w50 (royal purple). I know that it's great for the turbo but how about for the motor?

If you're going to use an oil that heavy, I wouldn't use RP. Shouldn't be too bad for the motor as long as you are in a fairly warm-weather climate. Otherwise the thicker weight (20w) at start-up will cause a little more wear than a 10w or 0w. Personally, I think the TWS 10w60 is the way to go if you need high operating temp weight while balancing start-up wear at cold temps.

Shell Helix Ultra 20w50 isn't bad either. There is also a Helix Ultra 10w60, but it's very hard to find and is extremely expensive (factory recommended fill on the Enzo). Pennzoil also makes a full synthetic 10w60 that is ~$9/qt and is factory fill on the 599 GTO/F12/etc.

Nice to see that TiAL reccomends that weight too. Mind posting the email?

[s4andtls]

I've used Mobil 1, RP, but Motul won me over, tranny too. I'm breaking in my 605 build now, 10w40 non synthetic.

Subject: Re: Proper oil weight for Tial605?

We would suggest running 20-50w synthetic through Royal Purple, or Mobile 1. You don't want too thin of oil as it will flow too much through the turbo and it could cause some backing up on the drain side.

So with that said, up here in good ol Seattle (area), the temps are COLD. I know they're recommending a 20w-50 and Fourplay mentioned that it's probably not the best on the motor. I'm assuming Pennzoil 10-60 would be the best bet for my climate? Car will rarely get driven in below 50 deg temps.

[dannyn424]

rocking mostly tdt 5w40 w mos2.. car seems to like it better than t6....seems to settle into idle quicker.....

10w60 will be the best bet I would think for lower temps. I don't know of any 10w50s off the top of my head. But in 10w60 there is a pretty good amount of choice (BMW TWS, Pennzoil, Helix Ultra, etc.). During the summer time you can run a 20w50 easily though.

Worth a read if you haven't seen it.

We speak with every customer and discuss oil choice based on their climate. Zinc content and shear pressure are the most important aspects. You can definitely run a lighter oil in colder climates. Some of the recommended oils are as light as 10w-30.
