Royal Purple Quadex

Quadrex® / Quadrex® Hi-Base

  | Product Sheet

Quadrex® is a low ash, fuel saving, high performance, synthetic blend 4-cycle natural gas engine oil.

Quadrex® saves fuel and reduces maintenance costs. It extends drain intervals, ring and bearing life, prevents piston seizing and scuffing and keeps engines clean.

Quadrex® is formulated with Royal Purple’s advanced proprietary Synerlec® additive technology, which is proven to make equipment run smoother, cooler, quieter, longer and more efficiently.

Quadrex® Hi-Base has all of the performance advantages of Quadrex®, but is formulated for gas engines using high sulfur fuel. When new, its sulfated ash is above 0.45, but in service, its synthetic solvency controls ash. This makes it comparable in performance to conventional low ash gas engine oils, yet it will still protect against the harmful effects of corrosive fuels. Quadrex® Hi-Base is available with TBNs of 8, 10 and 14.
