Review: Good value/ maintainer - This stuff is basically the exact same as Lucas UCL which I've used for years. The only difference is this is almost half the price. Just know going in, that this is intended to prevent a fuel system failure, not clean or " fix" an already damaged fuel system. Personally to me the 2 main benefits of occasionally using this is most importantly at #1- keeping the fuel pump lubricated which can prevent an expensive failure of an overheated pump, and #2- a slight increase in gas milage due to keeping things clean and lubricated. Very worth it to me, especially compared to the competition's price and the consequences of a fouled injector or burnt up fuel pump.

## Questions & Answers

**Q: is this ok for turbo engine?**
A: It is a oil thickener. I would not run anything besides clean engine oil through your motor. This product should only be used on older engines. If you want to help your motor, change the oil often, and save your money for cleaning out the fuel system, or changing air filter. Don't waste your money on oil additives, trust me...(;

**Q: This is a fuel addive. Can I use with a turbo engine?**
A: It doesn't say for turbo engine on the bottle, therefore I will not recommended.
