Do oil additives help or do they cause more problems?
perhaps you should try laying a pillowcase over it while ironing. if you turn it inside out to iron your creases will be inwards while wearing the dress. turn the heat up a bit, and use the case as a protection barrier.
their good some times. the oil additives that are like honey arent to good, they thicken the oil and when oil gets thick it increases pressure, and an increase in pressure in your lubrication system usually mean blown seals (most of time front/rear main seal)
If you do regular oil and filter changes and use quality products when doing so, you will not need any additives. They make so many promises that go unfulfilled.
I have read a few things regarding additives, and it seems most experts do not place any value on additives, and actually sometimes can cause problems. Better ideas are to use better quality oil and filter. Change oil at 4000 miles rather than 5000. If the car has higher miles, have the oil pan cleaned by being dipped in solvent, this removes sludge. Make sure PCV valve and valve cover breather hoses are replaced if needed. a
