Re: Spark plugs
It certainly is, and it is causing plugs to fail in older cars in less time than with the ol' leaded super grade. I look after a 280 Merc with the very hard working and high revving 2.8L motor. It does it tough with such a big car body to drag around! It was running like a dog about 12,000k after fitting new plugs. I didn't believe it was the plugs and I tried a few things, but in the end a plug change fixed it. The LRP blend fuel is what is dumping deposits on the plug tips and causing misfires.
And consider this - LRP is PULP sold WITH additives to make it suitable for older cars and sells for about 5c more than ULP. Any yet PULP by itself is 10c more than ULP alone. Do we have a ripoff or not?
