Always makes me nervous as f**k to get an email from BlackStone Labs...

So far, so good. Especially when I switched over to Liqui Moly 10W-60, since the MZ4 Coupe has had NOTHING but Castro TWS 10W-60 for the last 13 years.

Knock on wood. At 53,000 miles it's getting to nervous time, although the engine has always run strong with nary an issue.

But I am happy to report that the Liqui Moly works well and my engine seems to like it, and it saves me about 1/2 the price for each oil change. Also this is on a 2 year drain interval, as the car BARELY gets driven now since I work from home.

I think between the Vette and the MZ4 Coupe I drove a total of 5,000 miles last year, and most of that was from going to and from Laguna Seca and various other tracks in the neighborhood.

Nice results. I recently let my indy shop do an oil change, and they use good ole Castrol, but also soaked me for $25 for an OEM oil filter - uh, no. I have 6 liters of LiquiMoly ready to go for the next change, with an $8 Mann (OEM equivalent) filter. I used LM in my first coupe and have zero qualms about it, and the cost savings over TWS is huge.

Always like getting biopsy results...

Those look good!

Awesome report!
Great numbers....your mileage is LOW....great side-benefit to working from home; I re-purposed (AKA retired) 2+ yrs ago and drove 1,208 miles between annual oil changes....the Red Roadster is a fair weather car now (it rains on occasion in the Seattle area) and fire it up and go for an early morning top-down drive (no matter the temperature) weekly....my Blackstone report(s) have been great to-date.

Nice! I just changed over to Liqui Moly 10W60 as well after using Castrol 10W60 since 2007. Not for cost though. Mike Miller (Roundel Tech Talk) convinced me to. He is not a fan of the Castrol in terms of its viscosity. He recommended Liqui Moly or Red Line. It will be a while before my UOA, but yours is reassuring to me!
