No, a 10W30 is not a series savior, by the time the damage is done, nothing will save it. But as an oil that promotes long term engine life, had it been used in the beginning from the get go, the problem would not exist today.

Hard data doesn't lie. The Saturn S car has developed a reputation of becoming an oil burner with in 100,000 miles when using the recommended (by the factory) 5W20 motor oil.
And they are not the only one, but the one seen on this forum. The internet is full of related concerns with High mileage oil consumption on cars manufactured in the early 90's and now have that kind of mileage on them that have had a steady diet of a 5w something oil.
And this was predictable by the oil company recommendations as to viscosity usage from the era and frankly still is.
Yet case after case exist that when viscosity usage corresponded to viscosity vs temperature applications, the engines have performed admirably.
My own experiences show that when factory recommended oil of a 5W20 was used as a lubricant on fleet cars at the time that the drivers were complaining of the running hot. Something that too was predictable when driven hard. A change to a 10W30 or a 10W40 stopped that.
So like I said, once the damage is done it is done, nothing will fix it after the fact other than a rebuild, a questionable procedure on what is now an old used car of minimal value making the thought of a rebuild a questionable value vs the dollar spent. So using a heavy oil at this point in time may eek out a few more miles for the cost of a can of oil and diligent attention paid to consumption habit, but that has always been the universal approach to driving tired worn out engines.
