## Questions & Answers

**Q: Can this be used in a new motorcycle engine with wet clutch?**
A: Yes, although I don't know why you would want to. 
Motorcycle oils are already pretty rich in Z and P. 
Now if you are deciding to run a 15w40 diesel oil, you may want to boost Z and P slightly if it is CK-4, and this product is appropriate for that. 
An SG, SH or even most SL motorcycle oils are all you need.

**Q: Is compatable with my hyundai tiburon 2007 2.7 v6**
A: No, you have catalytic converters and oxygen sensors, this product is not compatible.  Use 5W-20 or 5W-30 oil as recommended by the manufacturer.

**Q: can you use this on a new car?**
A: A new car should have had the engine broken in at the factory.  The chemicals in this product aren't compatible with the oxygen sensors and catalytic converters in a new vehicle either.  This product is really meant to be used in an older pushrod type motor after it has been rebuilt or a high performance flat tappet camshaft has been installed to reduce cam and lifter failure.  I would not use this on a brand new car, I would use the oil recommended by the manufacturer and change it at the recommended interval schedule.  Oil additives aren't necessary and might void your warranty.

**Q: Can i use this product on my 2005 cadillac srx**
A: No, use 5W-30 synthetic oil that meets GM4718M specifications or whatever is specified in your owners manual.  The excess zinc and phosphate in Redline break-in oil is meant for hot rods with engines from the 1960's to 1980's with flat tappet camshafts, yours is a roller tappet engine.  You could possibly cause damage to your oxygen sensors and catalytic converters if you use this product in your Cadillac.  Look for oil that says Dexos1 (Dexos2 is for diesels) but remember to check that the oil meets GM4718M specs and is a 5W-30 synthetic.
