Ok, I have an 07 with 3600 miles on it. I added roughly 1 quart of oil between 280 and 2800 miles. At 2800 miles I had its first oil change done and the MSP16 reflash.

The car now has 3600 miles on it and appears to be using little to no oil. While I'm sure it's not related, I've been adding about 5 oz of Lucas UCL each fillup of 12.5 gallons.

This lack of consumption has me concerned (I don't trust dealers).

My driving is mostly highway. About 70 miles a day, mostly at 70mph.

Any comments/suggestions would be appreciated.

Do you rev it much? This engine will not ask for much oil unless you keep it near the red line. So if thats not happening much, start enjoying the 9K more. Here is the place where people are discussing this new Flash. How does it feel power wise?

Hello Old Rotor,

Well, I try to rev it to near redline a couple times a week. I did this probably less often in the first 2800 miles. I may just be paranoid here, allowing all the discussions here about replaced engines bias me.

I have noted very little carbon in the exhaust tips. There was more accumulation when it had fewer miles but I cannot say that's because of the reflash. Perhaps it accumulated faster when it had fewer miles.

I noted that there are problem codes for the OMP, and I don't think I have any of those (no CEL of course).

Power seems fine to me, runs great.

800 miles is not long enough to get a good read - also dealer may have slightly over-filled it at the oil change, leaving the impression of less oil use than is really going on.

In general , it is very hard to get a good oil usage read out of the sump as the dipsitck is not exactly an accurate measuring device when you have about 1 inch denoting 1.6 quarts of oil level and we only use about 1 qt every 2500-3500 miles on average. Also, some (but propbably not in your case with many highway miles) will have the appearance of less oil use from the condensation buildup that can happen in the oil when you do lots of short trips that do not get the oil good and hot often enough to burn off the moisture.

Old Rotor/Jax,

Thanks for the input and pardon my ignorance on this subject. This type of engine is definately new to me (I can't believe I'm asking it to burn more oil, lol). I'm a bit paranoid, no doubt. But I'm learning here. This site will prove to be quite valueable.

On another note, I'm wanting to do all my oil changes. I'm considering purchasing an oil change system as I'd like to find a way to get all the oil out while making it easier (I understand quite a bit is left after an oil change, as much as 3 quarts or so).

Here is one I'm considering: http://www.anchorexpress.com/product...l.cfm?pid=9418

Note, it simply evacuates oil from the oil pan throught the dipstick, so I'm doubting it'd do any better, and perhaps worse than a simple drain at the drain plug.
I'll continue to research this but if anyone has any ideas or comments, let me know.

Jax_RX8

Good Idea, but the one you are looking at is expensive and overly complicated. I also use an oil extractor and can get about 5 quarts (of the 7) out very consistently (more than most which are getting 4-4.5 quarts out) - with the added benefit of not having to jack up or crawl under the car since the filter is on top as well (at least through the 2008 models).

I use a Pela Oil extractor and it can be had here:

Kinda curious where do u stick the tube to ?

Cuz it sounds like a great product.

Jax_RX8

Right down the dipstick hole until you hear it hit the bottom of the oil pan. It has a long, thin tube specifically designed to do this.

I use it on two other cars as well - works great unless you have a car with one of the very twisted dipstick tubes - fortunately not the case with our 8's.

Ooooo ... sweet ....

hmm ... let me think about it ... Thx man

digitalSniperX1

5 quarts, fantastic. I'm getting one. Thanks a lot Jax...you're a wealth of information here. In time, hopefully I'll catch up and be able to provide some myself.

I'm really considering this right now, thanks!

DemonRX-8

Jax, you're saying you can get the full 5 qts out without even removing the drain plug? If so, I'm all over this thing!

Jax_RX8

Yes I get 5 quarts out, but remember that capacity is 7 quarts, so I still don't get it all.

DemonRX-8

Cool, thanks! Yes, I know it's not the full capacity, but it's better than you get with just the drain plug plus you don't have to jack the car up. Very convenient.

you could still jack one side of the car up (then the other side) while using the pump to get even more oil out.

DemonRX-8

OK, I ordered the Pela oil extractor. I can see where jacking the car will help, so I'll keep that in mind. Jacking the car is not that bad, just having to crawl under to drain that's a pain.

robrecht

Any reasonably priced extractors that get more of the old slimy stuff out? Or is that just not realistic?

if you really want to get the most out here you go.. this method gets most of the oil out of the coolers.

as to oil usage, the 1.75 qts between full and low. i do not hit that in 5 k miles of 98% highway driving..

i am on the t flash..

5 Quarts is pretty sweet already, consider that you dont have to jack ur car to do it !

Hmm, Im about to order it, but my next oil change is due like next month, I can wait

I had the recall done and had the same thing happen to me. Little or no oil consumption, but the did overfill my oil but it doesn't seem to be going down. I used to have to fill after every other gas fill-up. I have started to premix with Idemitsu thanks to Dominion and Phil's 8. This gives me a piece of mind knowing soome oil is getting in there.

digitalSniperX1

Well, I drove it a bit harder on this tank and what do you know...it used about 1/4 quart in 240 miles.

It was over filled just a tad.

I have been premixing with about 5 oz of Lucas UCL, but that's temporary till I get that Sohn device on this car....afterwhich I'll use the following:

Amsoil Saber Pro 2cycle through the Sohn system
0w20 Amsoil or M1. Leaning toward the M1 because it's additive package includes some moly, some boron and a reduced ZDDP level (SM classification I suppose). I have a hunch, but I think these engines like boron and moly.

robrecht

Sources inside Mazda seem to indicate that the reason Mazda does not recommend synthetic is because of some additive(s) present in some synthetics and Mobile 1 is specifically mentioned as one of the culprits. This from rg.

I am getting the Re-Flash done on Thursday 4/17/08.

AJ's Shinka

I'm going to run it hard the rest of this tank and see if there is any change.

digitalSniperX1

I'm pretty sure the Sohn oil adapter will allow for the use of any synthetic in the oil pan (I almost said crankcase)....the oil injected into the combustion chamber will come from the bottle under the hood (2 cycle stuff, made to be burned, not as much carbon formation in theory).
