i-Sigma Top 10W-40

Its formulation allows the longest oil drain intervals admitted. It is indicated for most manufacturers in particular for Scania engines. It can also be used in normally-aspirated diesel engines installed in vehicles engaged on urban and short-haul goods and passenger service, as well as in supercharged diesel car engines, providing a very quality margin.

  • Its detergent-dispersant properties, combined with its very high, long-lasting ability to neutralize acidic products of combustion, keep pistons exceptionally clean, while solid combustion products are held in suspension, thus preventing the formation of harmful crankcase deposits.
