I have always preferred Castrol Semi Synthetic myself. Been putting it in all my vehicles since Moby Dick was a minnow. I use 5W-20 which is called for by the manual and either a NAPA Gold or WIX filter. I'm pretty sure that NAPA Gold and WIX are the same. I never go longer than 5K on a oil change with always a fresh filter. To each his own just don't use a cheap filter and always use the Manufacturers recommended oil while under warranty and make sure you keep the receipts to prove the vehicle was maintained... HTH
My change oil light came on four the first time this week. Gonna change it tomorrow morning but haven't decided what to put in it. I'm leaning towards royal purple but is it worth the extra money? I can't find it in anything but 1 quart jugs and the best price on that is $8 a quart, can get mobile 1 for $23 for a 5 quart jug... Just out of curiosity what's everyone else running?
Mobile 1, 5w30 synthetic. Drove 30K with it on my former Grand Cherokee with same engine as my JKU, no single issue. Costco having this oil on sale very often.
