Low-viscosity oil field trials pushing fuel economy

    Low Viscosity does have advantages, it lubricates better and faster at start up, its circulates faster, you can build an engine with tighter clearances and use a thinner oil and not lose wearability but gain durability, many races have found this works and have switched to lower viscosity oils from the 50 weights they used to use. I have several japanese cars that use a 5w20 oil all year round and get nearly 35-43 mpg and the engines last with the highest mileage engine at 245,000 miles and it runs like its brand new….I use a Castrol Synthetic blend and oil changes at 6000 miles and Ive had very good luck with Low viscosity. strives to maintain an open forum for reader opinions.
