Our first 'Fuzz Townshend's Classic Oils' product was christened 'Heritage' in honour of our location at Bicester heritage, and is a high-quality multigrade mineral oil designed for later (post 1960) classics with oil filters.
Blended in the UK to Fuzz's own formulation, its high-zinc content (1300 parts per million) makes it ideal for engines with heavily-loaded rubbing surfaces, eg cam lobes and tappets. Made from carefully chosen base oils, Heritage stays in grade well at high temperatures - ensuring good oil pressure even under extreme usage, including racing!
Highly effective detergent additives ensure minimal levels of unwanted deposits on pistons, spark plugs and cylinder heads.
The formulation of this product is comparable to other brands costing many times more, as can be seen in the table below.
