## Description

From the manufacturer

Review: Great price - Good product at the best price.
Review: Good price for a trustworthy product - I prefer Magnatec, but it's becoming increasingly more expensive and difficult to find a deal. GTX is still a trusted and good performer, and definitely worth the money if you keep to service intervals. I avoid cheap engine oils like the plague, as they've never proven to come close to top brands, regardless of the oil spec printed on the bottle. Those who know, know the benefits of genuine brand engine oil 😉

## Features

- Contains MOLYBDENUM POLYSULPHIDE LONG CHAIN ALKYL DITHIOCARBAMIDE COMPLEX. May produce an allergic reaction.
- Safety data sheet available on request.
