Good for a high mileage engine.
From personal experience, this is the best product I have so far found for my 21 year old Volvo. The engine has covered 208,000 miles without a rebuild and still has excellent oil pressure. Minor hydraulic tappet noise on startup has been virtually eliminated. Read full review...

Probable good choice for older engines
If I use synthetic oil in My 2001 mm 4 golf the engine oil level drops - but no exhaust smoke
Using Castro gtx 15-40 the oil level remains completely stable
