Magnets because they draw the normal SWARF particles out the lubricant .

Synthetic lubricants because they lubricate so much better they pretty much stop the wear cycle dean in it's tracks wherever it is .

Until you use synthetic lubricants you'll never grasp how good they are .

Worth every penny and then some .

I rad a clapped out 1969 Honda 90C.C. Motocycle over 40,000 miles on synthetic oils and it ran sweetly until I parked it .

Synthetics always make trannies shift better too .
