Ok I'll try that too... It came out of nowhere, and only does it once in a while. Would you guys recommend adding more additive or draining it all and using synthetic?
Add more additive. Why spend $25 on 2 bottles of synthetic when a $5 bottle of additive will accomplish the same thing? If the additive doesn't do it something mechanical is wrong and if that's the case I'd bet on spider gears or a cross shaft is broke. Dr. Diff sells a kit to replace them if you need it
