Is this normal oil consumption?

cheshirecat · 02-27-2013, 03:45 PM

While it is true that "acceptable oil consumption" varies dealer by dealer, it does not vary as it applies to the oil consumption tsb.

This technical service bulletin is something all dealers must adhere to when dealing with this problem. Don't be afraid to print it out and bring it in if you've already done your measuring at home and verified that you are indeed in the "No Good" area as illustrated on the TSB.

Good point

The replacement block for me, on both my 350 and 370, was great.

Just expect it to eat some oil as it's breaking in. From what I've seen, it should be largely finished by the 7500mi mark or so.

New short block is fine; no oil consumption at all. Dealer did a decent job.

ZOperaMan · 03-03-2013, 08:30 AM

It is my guess that dealers make money on warranty work, if they're competent. The paperwork for my short block replacement included a good size bill to be reimbursed by Nissan.

While they do make money on warranty work, there's a particular line they can't cross when it comes to monthly reimbursements from corporate.

If they do too much work, it starts to look like they're just looking for things to replace and bill out to the manufacturer. This is the reason that some dealerships will be hesitant to repair things when you bring them in while others may jump right on it.

Just another reason not to stick with one dealer if they're not working out.

930.5 from my last oil change at the dealer. Follow-up oil consumption test scheduled at the dealer this Friday.

Judging from the dipstick, it looks like that is at least 10mm from the H point of the dipstick.

What do you guys think?

Yeah. The oil rings are toast on your pistons. It is pushing oil from in the crank area into the cylinder. And you have a 6spd. My service managers was saying it is more prevelant with the manuals.

With the type of consumption that Avantgti7 is seeing, would you notice large amounts of smoke out of the tailpipes and soot on the bumper?

Not necessarily - mine was using a quart every 2500 miles, and no smoke from tailpipe; no soot (although soot is usually a too-rich fuel problem, not oil). Engine probably burned the oil very efficiently.

New engine replaced under warranty behaves the exact same, in every way except the oil level NEVER varies between oil changes.

I can say that I had very bad soot on my oil burning engine- the cool thing is that you could tell what side of the engine had the problem has one tailpipe would soot up as opposed to both (true dual exhaust setup).

No smoke.

After the engine change, the soot disappeared.

In my opinion, black soot on the tailpipes accumulating over 1k miles should be considered a warning sign of possible oil consumption. The pipes will get dirty, especially with test pipes, but just a heads up .

What if you have a muffler delete (aam short tales)? Would you get some darkness on the tailpipes?

Kinda like when you run hi-flow cats, you would have some smoke when you get on it.

Yay!!! New engine for you!!!

930 miles and you're about 3/4 of a quart short... Motor is toast.
Thanks for playing, lol

cheshirecat · 03-12-2013, 09:38 AM

That kind of consumption warrants a new block.

avantgti7 · 03-14-2013, 08:36 PM

1145 miles from the oil change....
follow-up consumption test is tomorrow
I hope I fail!
