Well, I just installed it (Hyundai OEM filter) on the car with 5W-30 Havoline, and 5 ounces of VSOT (heated the bottle of VSOT in a pan of boiling water and mixed it with a half-quart of Havoline, THEN added it this time). It gets real loose, that VSOT, when you get it to 200 degrees! This will be my first dino/OEM filter change in 5 years, instead of M-1/Fram. Cold start tapping has always driven me back to M-1.
Maybe this will fix it, who knows? Thanks for the pix of the Hyundai filters, guys. I'll post in the morning whether it makes any difference with cold starts.
Laters!
