Oil type

SB did pass the time by typing:

The main thing synthetics have going for them is longevity. Where dino breaks down after about 3000mi the synthetics can go out to 7000mi.

I ran dino for a few years, then tried blends and synthetics. The engine ran quieter with the synthetic so I stuck with it. Seems to keep the lifters happy.

nope. Unless of course you use pancake syrup instead of oil. :)

LOL!

That created a rather funny aunt-jamima mental picture...

I thought synthetic was Man'gineered.

'Some' is, most that claim the label aren't.

The 'real' ones took the fakes to court, but the word 'synthetic' covers too broad a spectrum so the cracked petroleum products or 'fake' synthetics can use it.

Then you have snake oil like amsoil that will void an engine warranty because it can't get the approval the vehicle manufacturer's demand.

I run only 100% synthetic oil, 0 W 30 in my TJ and Crown Vic. Only synthetic oil is used in turbine engines. Dino oil breaks down ,and cannot take the heat. If it can stand the rpm's turned by turbines and not fail that tells me its far superior to dino oil.

Dealer in New Zealand uses Mobil S for engine oil in TJs. Just had it changed last week. The Jeep is still under warranty.

The synthetic used in aircraft turbine engines isn't really a fair comparison though, as it GAINS viscosity with temperature due to its additives, the opposite of auto oils. I was a helicopter pilot for a few years and the sludgier that crap is when hot, the better. If you used av type turbine oil in your car, you'd be in trouble quick.
