Mobil 1 Synthenic 5W30 10W30

The proof is in the pudding. I bought this car with 47k on it. I've driven it to 107k. The previous owner claimed to always used Mobil 1. I continued to do so. I always ran 5W30, changing it at 3k or 3 months. Just a good habit passed down by my father. Yeah, it's expensive, but in the long run, worth it. As the car aged, with the common lifter chatter, in the summer I started using 10W30. This seemed to cure the problem. When the chatter returned, I knew it was about time to change the oil. This year, on a whim, I decided to tear down the engine (due to a head gasket leak) at 107k miles and rebuild it with some internal mods. I took the block and crank to the machine shop. Virtually no wear noted. The machinist reported that the two outboard cylinders had less than .001" out of round. The two inboard cylinders and crank journals had no wear at all. All he had to do was polish them up. Not sure if it's the brand of oil, or just the fact that I've been goo! d about keeping it fresh. I've since changed my other vehicles to synthetic oils. I haven't finished building the car yet, but be assured, once the engine has been broken in, I'll be servicing with Mobil 1.

Pure synthetic motor oil, $4 a quart, worth every penny

I just had a religious experience involving motor oil. In addition to my Miata, I have a second, older car; an '88 Honda Accord. It has 158,000 miles on it and I decided to do a valve job on it last week to improve compression. Expecting to find nothing but wreckage below the cylinder head, I was amazed by the condition of the engine. There was virtually no cylinder bore wear - the ridge at the top of the cylinders was almost nonexistent and honing marks were still present all the way around the cylinder bores. I measured the cam lobes and they were within 0.005 of a new cam - amazing. Honda parts are incredibly expensive, but the valve guides and valve stems, according to the machine shop I deal with, were within factory spec. They simply ground the valves and put the head back togther. Cost me $68, cheapest I ever left that place. I use Mobil 1 10W-30 in my Miata as well as Mobil 1 75W-90 gear lube in the transmission and rear end. I change the xmission and diff lube every 10K, the oil every 3K. I think it's worth the expense since I don't have to ask to know that a new LSD in a Miata is more than a Kings ransom. Since I plan to keep my Miata until it's dead, I believe this is the best way to preserve the car. It was just mind boggling for me to take a car apart that I've owned since it was new and see what looked like no more than 10,000 miles of wear when I knew better. And that Honda has never leaked a drop of oil. I think all this business about synthetic oil being incompatable with engine seals is a lot of hot air. Whether refined normally or synthetically derived, oil is still oil.
