So pennzoil has a new synthetic out derived from natural gas... their claims are regular oils are made from crude oil which has lots of impurities and is a "dirty" oil... this new stuff starts off as natural gas and through some process they make oil out of it, the oil starts out clear until they add a few additives and then its a light honey color... they call it "clean" oil... anyone tried this new pennzoil platinum? my brother in law just tried it, and said the car even feels like its running cleaner... then again, he also had close to 8k miles since his last oil change.... pretty sure walmart oil would of felt cleaner than that black mud that was in there... THE CONCEPT OF A CLEANER STARTING PRODUCT MAKES A CLEANER END PRODUCT SEEMS LEGIT, BUT IS IT TRULY AS GOOD AS ITS SUPPOSE TO BE???
