Motorhome has Maxlife 10w30 in it and one quart is the Synthetic Maxlife. The oil has been in for 11.5 months and has 2700 miles (not that I don't enjoy oil changing, but I think there is life left in that oil). No short trips. Looks good on the blotter. I am taking a 1500 mile trip soon and plan to continue with this oil and maybe leave it in over winter, changing it before my spring trip. I have to change the filter now though because the existing filter has a rusty seam and that to me is risky. So I will need about 3/4 qt make up for the filter. Think I will throw in a bottle (15 oz) of this discontinued STP 6000-Mile Oil Extender, which has zddp and other stuff, presumably an anti-oxidant. Anyway, just though I would share all that and see what reaction I get. No VSOT suggestions please. This thing gets plenty of oil pressure on straight 10w30 and does not need thickening. BTW, the STP stuff is not thick.
