Engine oil RED LINE or Eneos

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.

Eneos 5w-30 full synth for my 06 WRX. It has a high zinc content.

I have exclusively used Eneos 0w-20 in this car - the non-Sustina version. This past oil change, I started using Eneos Racing Street 0w-20 as they're phasing out the OG 0w-20.

Both have worked very similarly for me. No issues with anything other than E85 dilution when I'm running it.

I run Eneos 0w-20. Lots of people love Mobil1, if only because it is often on sale at WallyWorld.

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

Eneos 5w-20 in my 2008 2.3 liter Mazda3. It's a Japanese-branded synthetic oil that you can get from Napa Auto. I've found that with Eneos, my Mz3 stops consuming any oil (in both my 2007 and 2008 2.3's).

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

Eneos 0-20.

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 had pretty great results from Eneos Sustina in my 2017 3.
