Soluble oil or Coolant

    Someone I know has been advised by a usually reliable source to use soluble oil rather than regular anti-freeze/boil type coolant in his Alpine radiator. Advice was given that "It's better to replace the hoses every 4 years than have to replace all the alloy in the motor". He lives in a warm climate where anti-freeze is not needed.

    I've always used a quality coolant with corrosion inhibitors and have
    no experience with soluble oil. Anyone care to offer an opnion on this?

    Thanks in advance, Vic

    Can;t comment on that.. but i know alpines will corrode quickly with the wrong coolant, and if you mix them. Use a high anti corrosion coolant and keep the same brand. Use a return system and make sure radiator and hoses are in good condition to keep the engine cool. Its better to stop the alloy rotting and sort the cooling in another way other than using high % (glycol?) products.

    That's a new one!

    I see several problems. Apart from the corrosive effect on rubber components and possible ecological problems with disposal, the main one is that oil has nowhere near the cooling capacity of water. Water has the highest specific heat (the amount of heat required to raise the temperature of a given mass) of any natural substance. Oil has approximately half the specific heat, so you would be almost certain to overheat if you substituted it for the normal coolant.

    Stick with an antifreeze specified for aluminum engines.

    oil and water

    The only place I like to see an oil mixed with water is when cutting steel.... Period,,,, period..

    No excuses,,, The person who told whom ever to put this into the engine hasn't had one blow up on a hot day in the middle of (A nowhere,(B middle of traffic(C Middle of trying to get away from a naging wife.. Or oh god, not Nebraska
    Use only a good grade of standard compatable anti-freeze and about(depends on your daily temps) 50/50 mix.
    You guys and gals have a great evening.
