 There are engine oils and transmission fluids currently on the shelves at auto parts stores, convenience stores, food stores, and other retail outlets that can cause harm to your car's engine and transmission. Yes, you heard correctly - Cause harm to your car’s engine and transmission. So read the labels and look for the codes that speak to the model year the product was formulated to be used in.

As shown below, if the label says the product meets API SA, it's motor oil formulated for use in cars built prior to 1930.  Don't be fooled, whereas there are very few cars on the road built prior to 1930, there are plenty of these and other obsolete motor oils and transmission fluids still on the shelves.

So read the labels and contact PQIA if you have any questions.
