Is the Ebay stuff counterfit or stock from the 70’s , as there is a massive difference in price. I know Opie isn’t always the cheapest even with their discounts but that is nigh on a third of the price.
Red line 75W 90 you’ll need 3 quart bottles, Don’t skimp it! or you could be sorry
When draining I left mine dripping for 24 hours it’s amazing how much still comes out after the first rush.
Thats what we use, knowing what we pay I can’t see how that stuff can be legit unless they just have stock they need to turn into cash or its counterfeit, Motul have had issues before with this.
