Re: Oil Change - Frequency?
one personal note... i put magnetic drain plugs into the previous cars i owned, and noted one difference between Quaker State and Castrol GTX... there was a noticeable bit of metal shavings "fur" on the magnet EVERY time i pulled the plug for an oil change for Quaker State, but when i switched to Castrol, the stuff picked up by the magnet was smaller in quantity and smaller in size of metal particles. more like a little blob on the magnet than a small spiked hairdo of metal fur with the QS oil.
i switched permanently to Castrol, and run their synthetic, now, if i have the choice.
fwiw...
