Our 188k mile Taurus started suffering cascading failures during a short holiday trip, and I didn't know if it'd pull thru. It's been getting hard to start, and it got worse on the trip. Oil consumption has been getting high, a qt every 300 to 500 miles in the city, every 1k or more on the highway, which is confounded by the hill that we live on as consumption driving up and down the hill seems to be a lot higher than when on road trips. I used some Mobil 5000 10W30 at the last change as I was intending to use some Auto RX, I usually add a couple of qts of Mobil 1 T&S but didn't this time, and oil consumption went up a lot. I went ahead and started adding Rislone instead of make up oil before the trip as it was advertised as an additive that you can keep in the oil instead of being a flush, and I didn't find any nasty complaints about the stuff. Some BMW mechanics suggested 3 1500 mile oil changes with a qt of Rislone for treating sludge. I suspected stuck oil control rings as I don't get blue smoke at start up, which is often a sign of worn valve seals.
On the trip oil consumption went up, I ended up adding the whole qt in less 300 miles. The check engine light came on after 2 hrs, which it has on previous trips. When I got back I checked codes, replaced the O2 sensor, and have been making slow success on the cold start problem, cleaning throttle plates and such. What's neat is that about 300 miles later there is no oil consumption. I'll leave the stuff in for another 1k miles or so, and will probably change to Mobil 1 T&S. I'll plan on using some AutoRx in the tranny.
Some snake oil articles stated that Rislone and MMO were products for the 50s and 60s, but with the superior engine and lubrication technology that we have now they're not needed. Now we seem to need AutoRX AND LC :^)
I'll consider using Rislone from time to time.
