First let me preface my question by stating that no oil can completely prevent engine damage if engine oil is heavily contaminated by antifreeze, fuel, etc. Understandably, large amounts of contamination can and will prove deadly to an engine. However, I'm curious if there are oils with certain additive packs (conventional or synthetic) that would help curb damage caused by these contaminants, especially if the contamination starts out undetected, in small amounts.
I'll give an example - my '98 chev. has the Vortec 350 that was infamous for intake gaskets that degraded prematurely, often causing antifreeze leaks. I replaced mine a while back at 118,000 miles, due to some external seeping. Luckily, I caught it before it started dumping any coolant into the crankcase, but judging by the condition of the original IM gasket, I didn't change it a moment too soon.
Let's pretend I didn't have knowledge of this issue and had let it continue seeping, possibly leaking into the crankcase. Or, for the sake of this hypothetical, let's consider fuel dilution, or dust / dirt from a dirty air filter. Are there any oils out there that would hold up better to trace amounts of contamination than others, in turn preventing wear despite the contamination? Maybe a high mileage formulation, designed for use in older vehicles more prone to oil contamination with age? Maybe any good oil would be just as effective? Maybe none of them would be effective? Been thinking about this one lately. Thoughts?
