Motor oil question

The place I use for oil changes offers regular, synthetic blend, and synthetic motor oils. I know that synthetic is best, but it's so costly. Is the blend of any use or is it just a waste of money? And does the brand make any difference? They use Valvoline.

Any oil changed regularly using a good filter will meet your Jeeps needs. If you change it yourself you can offset the cost of synthetic by saving the cost of someone else doing it. Personally I use Castro Edge with a Fram Tough Gard filter. I like the Performace I get from that combo. In the end it becomes a personal choice.

If you're here long enough you see the 100's of oil threads...which should I use synthetic or the end EVERYONE HAS A (PERSONAL) OPINION on it.

Thanks. I've read a lot if the threads including a recent one about diesel oil, but I haven't seen anything about the synthetic blends, so was just wondering if it's a gimmick like 89 octane gas.

Funny thing too is that most people think synthetic motor oil is made in a test tube somewhere. Your synthetic motor oils start out as good old crude oil just like all of the conventional motor oils. One of the reasons you can add a quart of conventional motor oil to synthetic if you are low. Not saying that the synthetic arent better oils, they are in my opinion but they are really "super" conventional oils.
The thing about using diesel oils was that they always used to have more zinc in them. The EPA really started making them cut back on the zinc in motor oils. Not sure what the zinc levels are in diesel motor oils are these days.

My vehicles get an oil change twice a year or every 5000 miles. Since my jeep is not my DD then it makes no sense to use Synthetic oil in it, however my DD (Dakota) gets Castrol Edge and a Fram filter and has since its first oil change.

I was in that industry for ten years. Synthetics are not necessary, and are not in any way, beneficial to run in these old machines. If you change the oil every 90 days like clockwork, nothing in that engine is going to wear out. New oil cleans the engine (which is what you want) but that property and ability diminishes in time. It's more about the frequency than the product you are using. Any 10W30 with a brand name filter and you will be great. Don't waste your money
Driving a jeep with a top is like screwing wearing a prophylactic. Maybe a little safer but doesn't feel nearly as good.

Thanks guys for your input. And Florida, that's what I suspected but just wanted to be sure.
