Re: Motor Oil said by DarkLogix:on my other car it ran dino oil for most of its 150,000miles and I have to have the rear main and some other gaskets/seals replaced
Gaskets and seals can leak, and I'm not sure how much dino vs. synthetic has to do with that. Some oils, regardless of base oil, may contain more detergent than others, some others (esp. high mileage) oils can have additives that swell seals.
My Bronco has some minor oil leaks, but it's not bad enough to start replacing gaskets and seals at this point.
it partly depends on how hard you are on your car too.

kudos:2 | said by aurgathor: Methinks you have to drive it really hard (i.e. racing), under some extreme conditions (cold or heat), or do extended change intervals to make the synthetic oil worthwhile.
Or towing, heavy stop and go traffic, mountainous terrain, and even just engines that run hot because the engine compartment is jam packed, and little air flow. Maybe you just want to give maximum protection to your mill.
For myself, all of the above apply. Just my choice, and MHO. |

on the other one I didn't
the dino oil that had been used in it for most of its life built up gunk on/around/in place of the gaskets/seals and over time it caused it to leak
on my current car it doesn't have a single leak, because the synth oil doesn't build up the gunk that dino does
ya hitting the 1/4 mile track is fun, nad I need to get around to going more again (stopped because it was annoying to get glasses on under the helmet that I have to wear due to my time, but lasik has solved that) |

No oil leaves any deposits if you change it on a proper interval and don't mix weights or mix brands in the crankcase....

If you're towing something heavy most of the time yes, but otherwise no; the other reasons are just plain laughable. 
For one, most engines are watercooled, and shouldn't run hot just because the engine compartment is packed.

kudos:2 | Air still has to flow, bro. The more the better, for the most part. I realize engines are water-cooled, but air is a critical factor as well. Tight spaces create hot spots. Why do think they have cheese graters?
I know you're old enough to remember an engine compartment you can sit in to change a plug. |

Engines in general - now run a good bit hotter than 15 years ago - hell - than even 10 years ago.
I think there are goods reasons to do synthetic and extend the oil change out for any car - but that is my personal opinion.. With the increased engine temps - I want the oil to break down slower than with pure dino oil doing more frequent oil changes.

Only through the radiator core as the block, heads, intake manifold, exhaust manifold are not air cooled one single bit. Plus modern cars have some of the smallest frontal areas compared to just 20 Years ago. Some having just an area open to airflow half the size of the radiator core.

Some engines -- yes, but the OP's car has a V8.
