Hey, everyone. Looking for a recommendation on oil for my Jeep. Did a search but only pulled up one thread on a Grand Cherokee. I may have googled wrong. 1999 Jeep Wrangler 121 k miles Daily driver and some light off road, though when I get my next daily driver this will become an off road toy. I drive daily an average of 25 miles each way to work and back, mostly interstate. Head gasket leaks, has for about two years, hoping to replace the head in the next six months. Lifted 4 inches on suspension, 33" tires, Mustang fuel injectors, Borla performance exhaust with rebuilt exhaust. I try to drive easy as often as possible, though when I'm late for work all bets are off. Been using full synthetic Castrol edge titanium for six years. Normally 10w30, though sometimes 5w30 when I change in the winter. Bosch premium filter. Try to change every 5 months. Kentucky, temps get up.to mid nineties in the summer, teens in the winter. Temp can spike up to 100 and down to single digits. Is 10w30 the best weight to run for my conditions? I've been happy with the oil so far, but curious about any full synth options. Also curious about opinions on filter. Thanks for any input!
