But I’ve been wondering about whether it’s still useful for a modern engine. And I’m wondering if they’ve kept the same formula or updated it. I’ve got a 2005 Crossfire Limited Roadster with 70,000 miles. I’m still using just the European blend of Mobil1 0W-40.

I think that if cars needed STPs ingredients then Mobil and other makers would add it at their refineries, all these additives are mostly ways to make money for their makers. The results to the user are none except to lighten their wallets.

Only additive I ever use is the occasional bottle of Techron, and I'm not even sure that does any good.

Have added STP engine oil treatment on every car I've owned. Cemented when I had a timing chain and gear on my GM 1989 Buick Park Avenue when I was a student in a tech college. Happened to break down in the college parking lot, and the auto courses instructor took it in as a project car (replacing the timing gears and chain). After he had his students tear down the pan and timing cover (also requiring an oil/filter chance since it all ended up in the filter and pan). he asked how many miles were on the car. I told him it was 140,000 plus and he couldn't believe it based on how clean everything was on the lower end. Showing him the service booklet (as I do all the recurring maintenance) he shook his head impressed with the condition of that 6 cylinder motor. All my cars get STP engine oil treatment when oil/filter is changed, my XF gets it every oil change since new (after first verifying it is 100% compatible with Mobil1 oils from Mobil1 when I first bought the car). I use 2 bottles because they recommend one for every 4-5 quarts oil. Been happy with it, and use it every oil/filter change.
