Thanks for taking a look at my ad. This is a service kit to fit the. Hi-Flo air filter (HFA3908). Hi-Flo oil filter (HF138). Four standard copper core NGK CR9E spark plugs (stock code 6263). 4 litres of semi-synthetic 10w40 Silkolene Super 4 engine oil. Silkolene Super 4 semi-synthetic oil conforms to the following technical specifications JASO MA2 and API SL and is supplied in environmentally friendly “lube cube” packaging. Using MC-Syn Technology, Super 4 oil protects the engine and transmission with advanced additive chemistry from start to full power. Detergents, dispersants and load carrying agents are incorporated to give excellent engine cleanliness and minimum wear of moving parts. A balanced blend of inhibitors and anti-wear agents ensure correct operation of oil immersed clutches and other drive line components. Silkolene’s “lube cube” packaging helps reduce plastic waste and pollution. This “bag in box” concept offers a smart, highly eco-friendly alternative to rigid plastic bottles and is easier to store and use. Each Lube Cube is constructed from a durable 100% recyclable outer. Inside is a 98% recyclable plastic inner bag, which after use can be flattened and disposed of in normal licensed recycling waste. The birth in 1908 of the innovative company that was later to become known as “Silkolene” was the vision of the entrepreneurial Dalton family of Belper, Derbyshire, England.
