I'm sure the recommended Dexos 5w30 SP, gf-6 will hold up just fine. Click to expand... On one of those 3.6s they 7500 is extended. Anything over 3000-5000 and they have a lot of timing chain problems! I'm a fan of 10K myself. But I don't own any vehicles with known timing chain problems from extended oil changes
