Phil Hristov uses Lucas Heavy Duty Oil Stabilizer in 1992 Honda Civic

My Civic has a to-date mileage of 316,500 km (196,663 miles). Before I started adding the Heavy Duty Oil stabilizer around 16,000 km ago, my engine wasn't turning over as easily on a cold start as I would've expected, was making too much noise at high speeds and shook like nothing else while idling. Enter Lucas Heavy Duty Oil Stabilizer: GONE! Engine purrs like a cat and runs like a well-greased gear and absolutely NO shaking. I am certain with repeated use that there's a good chance I'll attain my goal of 625,000 km (388,356 miles). Looking forward to my next use, my car thanks you Lucas Oil!!!
