Engine oil VALVOLINE or RED LINE

I run Valvoline simply because when I got my Civic people recommended it. Hasn't given me any troubles yet even in my Miata.

For my Ford I use motorcraft because it's oem.

For my high mileage Honda I've been experimenting with how the oil "looks" after a change. I know it's not technical but the valvoline oil seems to hold up well.

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

I've used Mobil1 many times but my last oil change I decided to use Valvoline 5W-40 MST SynPower which is actually on the list as a 502.00 oil.

Valvoline full synthetic 0W-20 changed every 5k, oil filters I prefer oem but recently it’s been whatever is on sale at advanced auto

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.

Just changed oil today (same oil as above) at 104,728 miles. Purrs like a kitten.

Valvoline Synpower 5W40 I've been running this (VW 502.00 approved) in our '07 Audi 2.0TSI for over 100K mlies, 10K oil changes, and no issues.

Valvoline SynPower Full Synthetic 5W-40, VW502 approved. I use it in our '07 A4 (over 100K miles) and plan to use it in our '16 GSW.
