At First I Had Trouble Finding The Right Weight Oil In Synthetic. But , I Ended Up Finding Some Royal Purple With The Right Weight. So , Now I'm Good. Also Just For General Knowledge. I Allways Had Herd You Couldn't Switch Because Of Possible Valve Ring Seals Going Bad. ??

You should not have any trouble finding 10W-30, and no you wont have any problems switching between the 2.
just dont mix it like 3 quarts of conventional and 2 quarts syn. its not recommended. and with a higher mileage vehicle ive heard its better to just stick with what youve been using, but if you want to switch to synthetic then do a part synthetic the first time, then do a full synthetic.
I was going to say the same thing! The Synthetic Blends try to give you some of the benefits of Synthetics but at a lower cost as it is mixed with Conventional Oil.
i was just going by what i read in a book. i want to get ASE certified in the next few years and i bought the 130$ book that the auto tech schools teach out of and what i said about the oils came straight out of the book.

Please do yourself a favor and learn the proper way (ie. under the hood of a car). Books teach you nothing about cars and engines, since it's all opinion and not fact. That book will at best teach you the basics.
Just my opinion, I surely didn't (and wouldn't have) gotten to where I am by reading a book.

Hahaha he's right. I learned really quick when somebody filled a ATF bottle with Mobil 1. I was running a little low on oil back with my last car and I poured a little bit of the "ATF" in there and wondered why it wasn't red.
You learn best from doing. Books are supplements.
Synthetic blend isn't as simple as mixing synthetic with conventional. It's a little more complicated, but not extremely involved. If I remember correctly, Synthetic blends are typically 70% conventional to 30% synthetic. If you simply mix both together, they will not be homogeneous. There's a bonding method that basically mixes them together under stress to make the solution homogeneous.
For example, if you try to mix powder creamer with cold coffee, it won't mix well. You have to either stir the &%*$ out of it or heat up the coffee.
i know you have to work on a car. i just read the book to try to learn as much as i can, just like the reason im on this site. i did ALL the work in my sig. and ive been working on cars by myself only for about 2 yrs. i didnt have anybody to teach me to install a cam, ive never even seen it done, but my "how to build a ford short block" helped out, and the cam install was a success. if i had somebody to work under or an opportunity to work part time at a garage trust me i would prob. throw the books away.

That old cliche comes from the refrigeration world actually. Back in the day when 134a refrigerant came out and everyone was in a big hurry to switch fro r12 to 134 they quickly discovered that replacing the freon and the charge oil in the compressor actually deteriorated the valve seals in the compressor. So the oil seitching myth actually stems from the refrigeration world.

When I bought my Ford racing crate motor, they reccommended 10w30 conventional oil for the first 500 mile break in. I ask what I should run after that and they said to just keep on running the conventional 10w30.
I think Valvoline conventional is excellent.
I use Valvoline VR-1 Racing Oil 10w30 because my car is street, but mainly used for the drag strip.
I think if you change your oil every 3000 miles or 3 months, which ever comes first, your all set, no matter what you use, conventional or synthetic. Plus using a quality brand oil is important.
I read a post, I can't remember where, in which someone had found the site where they actually grade the quality of all the motor oils.
Only a few oil companies synthetics where manufactured from top quality conventional oil .
There was a part in the article that stated, to cut costs in manufacturing synthetic oil, many companies start with a lesser grade conventional oil so that they can generate greater profits and be more price competitive. I don't know what companies do this.
I'd rather just use a quality conventional oil from a reputable company. That's just my opinion.
I like the way Royal Purple synthetic tarnsmission fluid works in my T-5z.
Regular Oil Vs. Synthetic?
