Longtime MX5 fan about to become a first-time MX5 owner. I’m buying a '90 Eunos for weekend fun and the occasional trackday, and wondered what engine oil (brand as well as weight) you experienced types would recommend. Opie Oils recommend 10W40 semi-syn, or 5W40 semi-syn as an upgrade, but I didn’t know if you knew better.
I’ve done numerous trackdays in other stuff over the years, but as this will be my first on-track outing in the Eunos, I want to make sure I’ve got the right stuff inside it first. So … any brand and weight recommendations are very welcome.
In anticipation, cheers!
