Great oil
Size: 1 Quart, Style: 6-Pack, Configuration: Euro 5W-40
OEM for many European cars. Have utilized for years in my 2 Fiat Abarth's, great oil at a competitive price and if you change oil yourself you save quite a bit as compared to dealers or other shops. No breakdown even with the excessive heat the little 1.4L turbo puts out, great oil to rely on.

Meets Chrysler Mopar spec for Wrangler and Gladiator 3.0 diesel
Size: 1 Quart, Style: 6-Pack, Configuration: Euro 5W-40
Cheaper than Walmart and auto stores. Meets Chrysler spec and way cheaper than the Mopar oil the dealers want to sell for the 3.0 diesel in Jeeps. You’ll need 9 qts.

Great oil for 124 spider
Size: 1 Quart, Style: 6-Pack, Configuration: Euro 5W-40
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.
