YuYuRena: Use ramps. Jackstands are too much work and the MSP has a high enough front end to drive right up most of 'em.
anarchistchiken, the lower numbers correspond to the "flowability" and hence lubricating properties of the oil. In layman's terms, the oil thins out when it gets hot: too hot/thin and it doesn't lubricate, too cold/thick and it doesn't flow. A multi-viscosity oil protects like a thin oil when cold and a thicker oil when hot - the lower number is how "thin" the oil can behave, and the higher number shows how well the oil behaves when hot. A 15W50 protects like a 15W when cold and a 50W when hot, for example. Racing oils are typically single weight - in that the racing engine is expected to operate in a narrow (and fairly hot) range, while a street engine must endure cold starts and so needs a thinner oil until warmed up. Thinner oils flow better, rob less horsepower, and work betterrwith tighter tolerances - so they're specced in more since manufacturing has become better and fuel economy more important. Older cars used 10W40 (thicker), newer cars 5W30. VW's love 15W50 (really thick syrupy stuff). Got it?
