Engine oil RED LINE or IDEMITSU

That's the wrong oil. You want the Idemitsu eco gold medalist advanced moly 0w-20, which is basically the same as Mazda oil(Idemitsu makes the mazda oil).

Idemitsu zepro eco medalist advanced moly 0w-20. Basically the same thing as Mazda's oil.

I had Blackstone do a Virgin Oil Analysis of Red Line 5w30 This sample of Red Line 5W/30 looks good in testing. The viscosity is just a little above our \"should-be\" range for unused 5W/30, but that's common to see with some brands, and it doesn't show any sort of problem or deficiency with this oil. The additive package is typical of Red Line. They use a lot of molybdenum anti-wear additive. There's also some silicon, which is good to know about since silicon can also show dirt in used oil samples. It's an anti-foaming additive. No moisture or solids were found. This oil is in serviceable condition.

I've run Redline in several previous vehicles.

I run Redline 5w-40. I do not use the 'Euro' formula version, but the regular 5w-40 meets the VAG oil specs for a (2012) TT-RS. I used to run Mobile 1 0w-40, but I believe that Redline, Amsoil, Motul, and a few others are a higher quality oil (ex: Ester base stocks for Redline and Motul 300v).

Hi Vr6oom, I have a 2015 S3 with 10.3k miles and also trying to reduce IVD and oil consumption as much as possible. After a bunch of research that I have done to find the lowest possible noack, saps for 5w40, which is the viscosity recommended. I have settled for redline 5w40 euro series, just got my UOA back from Blackstone after 5k miles and everything is looking fine for extended oil use. So far little to no oil consumption

The only one that I found that met my standards was redline 5w40 euro series. I have just got my uoa from blackstone and everything looks fine, so for 5k miles on it and no oil has be added.

I switched to Redline 5w-40 at my last oil change, just barely into my second round of it now. So far so good.

If you're looking for high moly content, I like Redline oil. Google it, there's tons to read on Bob is the Oil Guy alone. That, as well as Motul, have been great in my 2.0T which is pretty hard on oil.

You don't need to add any more additives to modern day oils. You said you will be using Mazda 0W-20 oil? This is one of the best 0W-20 oils on the market. It is made by Idemitsu for Mazda. It has very high Viscosity Index of 221. Most 0W-20 oils are around 170. This means it is one of the lightest 0W-20 at start up. This is what you want in the winter.
