What oil?

Idle control valve, clean it.

Already replaced it

Its always very loud and the revs fluctuate the first couple of second (30s tops) before it settles.

I’ll continue to investigate but those first 30 seconds or so are definitely more pronounced in the Winter months.

What kind of noise is it? Might be worth posting a separate thread.

5w50 is the best compromise in my opinion. For a regular usage car, is best to have an oil that makes the engine run cooler and allows better flow during cold starts. 60 grade oil comes in need when wringing the car much and in hot conditions, other than that is overkill and perhaps more detrimental than not.

Has anyone run Valvoline VR1 consistently and had a good experience? Was thinking 5w50. It's high in zinc, seems just right for an S54.

Doesn’t sound like an oil problem. It sounds like something else is wrong, e.g. an exhaust leak. Best to figure that out and fix it.

Switching to thinner oil might actually be worse. When an engine isn't running right, it'll usually dump a bunch of fuel and other contaminants in the oil. Thinner oils generally don't cope with that as well (there are exceptions but that's the rule).

What do you mean by sensitive? What's it doing?

I’m thinking of changing out of 10W60.

My motor is a bit more sensitive to cold starts.

Anyone running Amsoil on their race/track car?

I’m on my last set of TWS and thinking of what to try next.

Does anyone have thoughts comparing 5W50 vs 5W40?

Bimmerworld lists 5W40 as optimal for cold conditions but wouldn’t the 5W50 still be better for Summer months?

I've been using Redline 10w-40 for a long while now and the engine feels happy. Awesome oil pressure at all times, so far haven't had the need to go to a thicker oil.

IamFODI Is there even a shelf life of oil say I want to stock up on a couple dozen liters of tws or rav?

AFAIK the only potential issue is that some of the components can start falling out of suspension after a while, but it’s nothing a good shake can’t fix.

[jet_dogg]

I have never done it but it's totally legit and they will refund ya.

I couldn't be bothered I'm a lazy git.

It's kind of a pain in the ass. I did it for the past few oil changes on the DD (cheap 5W30 Pentosin kits) and I'm not sure it's worth the hassle and potential mess. Now, if the oil change kit is closer to $100 like the 10W-60 kits are, maybe it's a different story.

Props to you guys for doing that man I wouldn't have the energy.

Wait, so you guys are shipping used oil back to fcp? Thread is too long for me to thoroughly read every post.



If the above is true, it's because I'm lazy is that a good enough reason?
