A: Yes. There is still some confusion about changing to a different type of oil in vehicles, particularly older models that have accumulated many miles. A small group of mechanics and techs still maintain old beliefs that synthetic motor oils cause roller followers to “slip or skid,” or that switching to synthetic motor oil causes issues in older engines, particularly oil leaks. Facts have since replaced these outdated ideas. Both synthetics and conventional products are held to the same minimum industry standards, like seal compatibility, to make sure they can be safely used in the intended applications. The use of synthetic lubricants is growing rapidly in new and older applications because properly formulated synthetics offer benefits well beyond what conventional and synthetic-blend products can provide. It’s perfectly safe to switch a vehicle to synthetics at any time.
