The problem with calling Syntec synthetic is that you should get what you pay for. The courts go one way, one time, than change. An example? Years ago GM started putting Chevy small block engines in Buick, Olds and Pontiac cars. Along came a lawyer that took GM to court over the practise. GM said the small block produced more power, used less gas and required fewer repairs. GM said they did this to save customers money and give them a better product (choke). The lawyer won and the judge said that if someone bought an Olds, for example, he should get an Olds engine and so on. Big settlement. Then GM marked all their documentation and window stickers with statements like 'GM engine' to keep them out of court. The judge wanted truth in advertising. The judge in Syntec vs Mobil 1 went the other way. The judges are what the lawyers make them. Get a better lawyer, get a better judgement.
