F430s are in the low 100s now. Definitely an expensive car, but somewhat budget in the exotics realm.
Everyone I know who's in that segment didn't there by burning money needlessly. If an off the shelf euro oil does the job and you don't have to deal with shipping, getting free replacements from FCP is simply good finance sense.
For entertainment, go read ferrari chat oil posts sometime. There's guys running M1 0w40, Valvoline 5w40 Euro, the full gamut of $5-6/qt parts store oils. And then there's the guys insisting that the dealer-spec oil "foams" and causes untold damage--so you have to run 300V, Redline, etc.
This guy's car is long out of warranty, spec is irrelevant. As discussed many, many times on other threads about much cheaper cars.
