What weight synthetic oil do you suggest for a supercharged 2001 bullit with intercooled novi 1000.... asking for a friend.... car is driven in florida heat..
Stick with regular dino oil to prevent blowby and change it frequently. I used to use synthetic, and I have since switched back on the advice from Tim at MPH due to oil blowby.
I use 5W-30 because thats what my manual on my car says in 1999. I'd say go with whatever the manual says and you should be fine. Good luck!
