328 Maintenance Schedule

Ferrari 328 GTS

This information is taken directly from the 328 Owner’s Manual. It covers the Ferrari 328 GTB and Ferrari 328 GTS. These are the 1989 specs, yours might vary but you’ll get the idea. (Note: This doesn’t include updates from service bulletins and everything should be confirmed with your mechanic.)

This is here for three reasons:

1) The owner’s manuals that I can find online are too small & blurry to really read all that well and since they are in 3 languages, they are cumbersome to read.

2) There is a TON of misinformation and disinformation out there, mostly from people who read message boards and don’t bother to read the manuals. A little deferred maintenance can be much more expensive than just doing it right.

3) As a way of informing prospective 3×8 owners about what lies ahead. After reading this some might opt for a Toyota instead.

So let’s get into it and remember, this is direct from Ferrari.

Replace engine oil and filter. – 600 to 1000 miles then every 6250 after that. (I have to believe that you should change the oil more often than this. I’ll look into it but I’d do it every 3000-3500 or so.)

Check gearbox and differential oil level – Every 6,250 miles.

Replace gearbox and differential oil – Every 12,500 miles.
