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.
