Have used twice and in conjunction with Forte seal conditioner. Oil consumption much reduced but still some excess oil being burnt as o2 sensor getting sooted up. So may some other issues but overall product has worked somewhat.

Used it on my old Honda civic that has slight rod knocking. Now engine runs much quieter with no knocking. I Can’t comment on the oil consumption at this time. Still waiting to try it on my two BMW that burns 1 quart oil per thousand mile.  I would love to come back and provide an update if I could.

Helps with oil burning issues in an engine. Its almost like an overhaul without the heavy cost. Do ensure that the smoke is caught early and do not expect miracles when the engine is too far gone.

At US$60 a bottle (including extra $20 US import tax), very unfortunately it does not work to reduce oil consumption on my '05 325xi. The vacuum mod has a much better result at a cost $2 vacuum line.
