Hello all, here to talk about oil, though not in the way I see generally discussed here. On my JL I will be changing the oil according to the service life remaining on the vehicle. Long gone are the days where I would change oil every 3k miles (except my Subaru which burns enough oil by 3k miles that it needs an oil change). Like many here, I'm sure, I will be switching to a full synthetic oil once my free changes are done. My understanding is that this engine runs a semi-synthetic blend from the factory. Many of the better full synthetic oils promise a longer service life than traditional or blend oils. So my question is, how does our service life monitor work? Does it simply log your RPMs, acceleration habits etc in order to determine what it believes your oil life is? Or does it have viscosity/partical sensors that actually determine oil condition? The reason that I ask, is that run of the mil blends probably require changing much faster than say a 10-15k life synthetic oil. So if the system does not actually analyze the oil, this monitor would likely be off after switching to a higher quality oil.
