Hey guys, I'm new, and been doing lots of reading here. I have Jeep that mainly only gets used to for fourwheeling, it doesn't get driven daily, on fourwheeling trips it may have a 2-4 hour highway drive to get to the trails, and then it will usually spend 8-10 hours on the trails basically idleing. I try and change my fluids after each trip, which has been my justification on using cheap fluids. Heres what I've been running, Motor Oil: 10w30 Havoline (Switched after some intial reading here). This trip out I'm planning on running Castrol Diesel Oil (15w40), since my oil pressure is a little low, and the Castrol still claims to contain zinc, which is good right? My buddy said he adds a little gear lube to the motor at each oil change to increase the metal content, is this a good idea? Axles: Coastal 80w90 (generic stuff) gear oil, and been running 20% Lucas Oil Stablizer. (Read thats bad, so I think I'll stop with the Lucas) Transmission: Coastal 80w90, 25% Lucas Oil Stabilizer. (Again I think no Lucas would be better right) Transfer Case: Valvoline MaxLife ATF Bearings:Coastal Marine Grease All my seals and such are new at this point, so the water containmenation of all my fluids has slowed down, so using a little nicer stuff wouldn't bother me as much now. Any recommendations? Any opinions are appreciated.
