Engine oil OEM Mazda or RED LINE

Used to use Motul, now switched to Red Line for the higher zinc content and high heat stability. I rallycross my daily so high RPM and high heat.

Redline 5w 40 since break-in, 254k miles later engine still going strong. Plenty of other repairs done, but no internal engine repairs required.

Remember that the rotary engine burns oil by design and does not particularly like eating synthetics. Expect to use old fashioned dino juice and change your oil every 3000 miles.

Completed my first oil change at 5k miles with Redline 0w20 and a Mann filter.

Although this is exact replacent, mazda OE still uses Mazda branded GF-5 which is exactly the same oil but branded Mazda....

Love these high molly low viscosity oils. Absolutely the best out there

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.
