Welcome to Vapor Talk!   
You've gotten a lot of very good advice from @Walt. I'll add a few things too, even though I'm not familiar with your mod.
First, we call it 'juice' or 'eliquid', there isn't (or shouldn't be) any oil in the liquid you use to vape. If there is, I would dispose of it and get liquid that has VG (vegetable glycerin), PG (propylene glycol), food grade flavoring, and nicotine (as Walt said, either regular nic or salt nic). Sometimes there's also food coloring but I tend to not go that route, I don't want anything more in my liquid than minimally possible.
That said, since you're just starting out, I wouldn't buy any quantities of one flavor of e-liquid right now. The reason behind that train of thought is that you are just now quitting smoking. Your body is going through a lot of changes detoxifying from all the carcinogens that cigarettes contain. Your taste buds are changing too. What tastes good to you today in e-liquid form may not be as good to you tomorrow. When I first started, I went through flavors until I had well over 40 (that's probably on the low side as I went a little overboard experimenting) and switched around as my mood took me.
If you're switching flavors, you'll want to have a different tank and coil to keep it in. Using the same coil for different flavors may wind up giving you a happy accident of a good flavor or it could be a disgusting mistake. There is a wick inside the coil that soaks up e-liquid. This wick will retain traces of the old flavor so you really want to have a different tank - it's easier this way to just change out tanks.
Repeating Walt again, start with a low wattage level, you don't have to use what's advised, just start at something low and vape. If that's not doing it for you by giving you the flavor and vapor you want, turn it up just a few notches and vape. Repeat until you get a slight burnt taste. Back it down a bit. That's how you find your "sweet spot." As your coil ages, you may need the turn it up a bit. When you use your coil to heat up the e-liquid, the e-liquid will leave some gunk behind. The more build up you get, the more resistance it creates. The more resistance your coil has, the more power you'll need to heat the e-liquid to get the desired results. The darker, sweeter e-liquids will gunk up your coils faster.
Vaping will dehydrate you so start drinking more water. Don't increase your liquid intake by drinking soda, coffee, tea, juice... whatever. Just plain water. You'll thank me later. 
Sorry for the long post, but I hope some of this will help. Good luck, and ask lots of questions. We've all been there, done that, and want to help new vapers get off cigarettes.   

It's a decent mod.  I did a review on it here:   
 

That all makes sense, especially the "world around us going nuts" part.  I find myself popping it into my shirt pocket when I leave the house.  The more I use it, the more I like it.  I may bond with it yet.  

Sadly, the fear mongers will fail to read any of these conclusive studies and continue to spread misinformation. Still, it's nice to see that more studies are being performed and the same results are coming out. Maybe some day the mainstream news will pick up on it. One can dream...
Thanks, Walt, for putting up this post.   

Man, but I wish I were a bot! That way I wouldn't be so freakin' tired all the time.

Still vaping the FLaN, but I find that I chain vape it too much because it's so smooth. The berry mixes are acidic, and with the higher salt nic, I find I can take a few draws and I'm good for awhile. 

Nicely done, @Walt, and you didn't even need to put in any spammy links with your explanation! 

Here is one of the best descriptions I could find on the replacement coils:
 
SMOK TFV8 Turbo Engine Coils Features:
Patented Turbo Engines Coil Structure V8-T10 Deca/Decuple Coil
Patented Deca/Decuple Coil Design Kanthal Clapton Coil Material Turbo: 10T 0.12ohm rated for 50~300W, recommended 130~190W V8-T8 Octuple Coil
Patented Octuple Coil Design Turbo: 6.6T 0.15ohm rated for 50~260W, recommended 120~180W V8-T6 Sextuple Coil
Patented Sextuple Coil Design Turbo: 6.0T 0.2ohm rated for 50~240W, recommended 110~150W V8-Q4 Quadruple Coil
Patented Quadruple Coil Design Turbo: 5.0T 0.15ohm rated for 50~180W, recommended 90~150W V8-X4 Quadruple Coil
Double-Barrel Pistol Design CF Mate (Cloud & Flavor Balance Core) Turbo: 4.0T-X 0.15ohm rated 60~150W, recommended 80~120W V8 RBA Head
18mm Build Deck Two-Post, Dual Terminal Design Turbo: 4.0T-X 0.28ohm Fused Clapton Dual Coil rated for 50~140W V8 RBA-16 Head
18mm Build Deck Two-Post, Clamp-Style Mechanism Turbo: 5.0T-X 0.16ohm Fused Clapton Octuplet Coil rated for 40~100W They make a ton of these things and other companies also make coils that are compatible.  Higher resistances will give you better battery life but possibly less vapor production.  Flavor is hit and miss and the best way to know is try a few.  
 
Good luck!!

My advice is to not post gratuitous spammy links with your question. Thank you.

Hey Tam!
I make a berry custard for my wife she adores.  
still going strong....and no pod system yet.  I've fallen in to too much of a routine.  oh well, what ever works and gets you there.. 😀

Nice to see you again, @Bebop! 
I'm vaping some mixed berries with a drizzle of custard today. 

On the pod systems I've tried lately, once the juice goes into the battery part, the rest is just toast. Time to throw it out and start with a new battery unit.

The ones I had did have air holes in the very bottom, but I guess different brands have different designs. I tried cleaning the ones I had with rubbing alcohol, and it did help for awhile, but went bad again. About the only thing you can do is get a different setup that uses a fire button instead of depending on air flow to fire it. Don't know about the one you have, but mine had a hole through the middle of the contact pin for the air to flow, that's how juice got into the electronics.

Thanks Tam, PM sent

The FDA may also put a big dent in the vaping industry as well. Ah... the times we live in.  😡

The only reason I can see for a mod maker to recommend using a certain brand of battery is probably the same reason Chevy recommends using a Delco  battery and Ford recommends using a Motorcraft, there is probably some kind of Corporate connection. I use mostly  Kanger mods, and the instructions say to use a suitable 18650 30A battery, I use LG HG2 batteries that are rated at 20A, continuous. Kanger doesn't say 30A continuous or pulse.  (I haven't blown myself up yet)  The brand of battery doesn't matter as much as the quality of the battery, Samsung, LG, and Sony all make quality batteries.

You're all good.  The Samsung 25R is a fine "high drain" battery.  
If you're interested in digging deeper, put "battery mooch" in google.  Mooch tests batteries specifically for vaping.  

"Squonk"  is just another word for "squeezing the bottle."   

I vote for Vapor Talk, which is not on your list, but is the place where you posted your poll...

See what happens when I don't Google the mod first? I automatically assumed it was a regulated mod. Thanks, @Walt, for the correction!
Now that I know it's a mech, it's that much more critical and very important to stop using it if it's heating up as much as you say. Time to research how to use a mech before something goes wrong. Glad you came here to ask questions!

Sorry about the delay,
This is a mech or mechanical mod.  It has no circuit board and no safety protections.  It is basically a battery, a switch, and the coil you build.  The only safety protection you have is your knowledge of electrical characteristics of the coil and the battery.  The understanding of both Ohm's law and Watt's law are necessary.   
Please start with watching the videos here:  https://www.youtube.com/channel/UCePHh3NMvu3rW2LFJeOWo-Q
This gentleman is known as battery mooch and is probably your best source for learning what you need.  After gaining an understanding of the physics involved you can use this website to assist you in designing coils for the device:  http://www.steam-engine.org/wirewiz.html
The kit you have can be a wonderful device but it can also be hazardous if you do not know what you are doing.  

What resistance is your coil and how many watts are you using on it?

You nailed that!  Exactly!  This scenario has the potential to be catastrophic.  I also wonder if there is a chance this could happen while the mod is unattended.  Glad it wasn't in my pocket.  That would have just burned my arse!
