if you "Think" you're using the best for your car you can rest better at night. We have many "best" oils out there so you can use any of them without regret.
I just bought my first bottle of redline the other day. 0w40 powersports oil was on sale (still a ridiculous price so I only bought one). Other than that I've never used it because of price but if price was no object I view their oils as my top pick.
I was thinking of using a fully synthetic 5W30 engine oil in a 1.4litre TSI turbo-charge VW petrol engine that normally requires a VW 504.000 approved oil (to protect the catalytic convertor apparently). Royal Purple HPS is not VW 504.000 approved but they assure me that it exceeds VW 504.000 and will be fine. Is there anything else that is better that I should be considering?
