Being new to the forum this may have been covered but couldn't find the info I'm look for. I've been using the Valvoline premium conventional oil for sometime now in my other vehicles. I have recently picked up a 2010 ford explorer w/4.0L sohc engine. Would it be better to use a full synthetic oil with this engine or would the premium conventional work just as good? I've read about all the problems with the timing chain in this engine. It got about 109,000 on it now and have no problems as of yet. I change oil about every 3,000mi.
Appreciate any info about this.
TIA
