Since it is pure petroleum, it can safely blend with all other automotive lubricants, even synthetics, aft and mineral oil. It keeps old engines alive and new engines new.

## Questions & Answers

**Q: Hi.could you tell me if it is suitable for a Ford type 9 gearbox. Many thanks**
A: This product will be fine as long as your using a standard gear oil like 75w-90.

**Q: Hello. if it's this oil suitable for petrol engine and automatic transmission? im looking for audi a5 2009. many thanks.**
A: If you go on their site in USA it will answer it, Mr Lucas is no connection with Lucas electrical and was an expert at Moreys Oil/petrol additives which  are superb and I have used for years, but cannot get in UK after Covid started. Lucas is the same brew, read reviews from Lucas & Moreys for high mileage and engine protection, put it in my Lexus CVT auto box, but Audi I am not sure hope this helps
