One must consider the fact that the mfg is in business to make money and the majority of products are designed to last for the warranty period plus a little. Dealing strictly with the issue of lubrication, the most important thing is use QUALITY CONSUMABLES! Don’t go looking for the “cheapest”, go looking for the “best”. Amsoil has been the leader in automotive synthetic lubricants for decades and were one of the first companies to produce a “full synthetic” oil. Yes, that’s right, a modified mineral oil can qualify as “synthetic” when in reality it is not (that’s what happens when you let politicians stick thier noses into things best left to be policed by private industry). Thus, the first thing is to find a “full synthetic” product. Then you’re going to match the full synthetic oil to the operational conditions of the vehicle as well as to the environmental operating conditions. While it is easy to suggest 0w40, that may in fact be a bad choice for the application because a straight-weight 30, 40 or 50 may provide sufficient start-up lubrication without giving up protection on the top-end as all multi-viscosity lubricants do - lubricant must be matched to the specific application and the lubricant mfg is the one who knows their product best (and often times knows the vehicle mfg product better than the vehicle mfg does)
Oil filters are NOT created equal either. While a filter may “meet” a vehicle/engine mfg spec, those spec’s are loosely applied and are worth about as much as printing them on used toilet paper. Certain filters, like the orange ones, have managed to “meet” engine mfg’s spec’s for years despite the fact the cardboard disc would fail allowing oil to bypass the filter element and many times the filter failure resulted in engine failure. Go with a known good quality filter such as Luberfiner, Baldwin or Donaldson and let the “cheap” ones rot on the store shelf rather than wrecking your engine.
The absolute most important thing is check the oil level. Even if you run cheap crap oil and a cheap crap filter, running low on oil is still far worse than running on junk. Filter changes are very important especially with synthetic oils. The synthetics can work wonders and last a lot longer than any conventional oil but all is wasted if you faile to change the filter! If the mfg calls for a 10k or 15k change interval, at a minimum, you should be changing the filter every 5k and topping the oil off accordingly. In city/short trip driving, the filter should be changed every 3k miles. Sure, the oil will easily last 10-15k miles but ONLY if sufficiently filtered!
