I use Pennzoil Platinum Euro Full Synthetic 5W-40 in my Fiat 124 Spider, and it’s been great so far. The engine runs smooth and quiet, and cold starts feel solid. No issues with oil consumption, and it holds up well between changes. The 6-pack of 1-quart bottles is convenient and makes it easy to measure out exactly what I need. Overall, it’s a quality synthetic oil at a good value. I’ll keep using it in my 124 Spider.
