I was doing the math based on my mileage 6oz per fillup , 1 fillup per week (64 weeks) adds $1.50 per fillup... and will last me over a year....

Yeah that math sounds good....


so I have another question that has been posed by a friend who is a design engineer for a major oil company... starts with an E ends with an N. (he is an electrical engineer not fuel based) if we are premixing x amount of oil into the fuel we would be effecting the flashpoint of the fuel. the whole point of 93 octane over 87 is an increased flash point to avoid preignition.... I wonder if premixing effects the flashpoint enough to use 87 instead of 93? anyone know enough about this to intellegently answer this question?

 

I use this same method. Doesn't get much easier than this. I just wish the bottles held 1 more ounce.

 

Heh, I made this the other day. It came out pretty good I guess. Now I just have to figure out a way to secure it in the trunk!

 

lol thats sick! what did you make it out of lol

 

Screw the complexity of my previous idea; I decided to just get a 32 oz. bottle of Lucas UCL and use it up waiting for my box of Idemitsu to come in the mail.

 

Anyone interested in a group buy on Idemitsu premix and or engine oil? Looks like we can get $58 plus shipping from california.

 

I just use the Idemitsu containers themselves; one empty for measuring and the other for housing the oil, no funnel need and fill up the empty one with the amount of oil you want to premix then fill it up some with gas to pre-premix it before tossing it in my tank 1/2 of filling up. Both containers are strapped in where the OEM tire inflation kit goes.

I'd be in if we get enough people, I'll buy a case of 12.

 

Oh sure, just as I get my case in the mail does someone suggest this.

I'd be up for getting another.

 

I was planning on purchasing my case this weekend so this works out timing wise...

 

paimon.soror NICE set up!!

 

cut 2 holes and pass a belt over them. Buckle it up to the OE tyre kit (or was it oil?) belt on the deep right of your trunk.
Done

Nice paranoid setup!

 

Do the slimline bottles fit just right to open the flap in the fuel door, or do you still have to hold it open with something else? Just don't have it all right in front of me to check it myself.

Just got my Rx8, and was going to get some Idemitsu anyway, but I do like the idea of having something professional looking to hold it all. Though, I'd prefer more of a box to replace the tire kit in the corner of the trunk, that looks similar to it, or something.

 

Ha, why paranoid? I know where I want to put it, just haven't decided on the method yet. I'll figure something out.
I took a bunch of pictures of how I made that thing, but I accidentally deleted all of them off my phone. It'd made out of the clear cover for a 150pk CD-R spindle, haha.

 

Paranoid because all you really need is a 1kg of oil in your trunk and you're set to go

 

There's a flap in the fuel filler? If that's the case, mine's been missing since I bought the car two years ago. Makes me wonder now...

 

There has been enough interest so this is happening. Should be able to start having the cases ship the in about a week and a half.

 

-Woops, haha-

And about the cases of Idemitsu, how much is it gonna cost?

Edit: Just noticed York, heck yeah Shell!

Second Edit: I guess I was thinking about my Mx6, my Rx8 doesn't have that little flap. Makes things easier then, haha.

 

hell to the yeah..

 

I wanted to provide an update to this thread. One thing that did not occur to me when I started this thread, is that the RX8's fuel filler does not have a flap in it. When I premixed my old rx-7s part of the purpose of the funnel was to hold the flapper open when you poured in the premix.

With the RX-8, and an idemitsu bottle, there is no need for anything other than the bottle itself. It is more than possible to poor it in without spilling a drop.

 

^ I agree, with idemitsu its pretty easy to get your pour right, but the Amsoil bottles are a bit awkward and the dark color makes it hard to get an accurate pour lol

 

$58 plus shipping from California. Shipping cost per case will go down when you buy more then 1 case shipped to the same address.

 

Where do we sign up for the group buy, anyway?

 

I have to figure that out.

 

Ah, well, since I'm all the way out on the east coast, I don't see it being too much cheaper, haha. I'll go on and say, my zip is 23111, if you wanna go on and see just how much cheaper, if at all.


And yeah, I hadn't noticed it doesn't have the flap there until the other day. Shoot, it also doesn't have a little bracket to set the fuel cap on so it's not dangling either.. Ah well.

 

I still premix with my MM tune... Can never be too safe, rather safe than sorry...
