Low-emissions oils are expensive!

Recently got quotes for Chevron Delo 400 LE 5w30 and M1 Delvac 1 LE 5w30. Both are in the $8/qt range.. for cases of 3 or 4 gallons!

Do you specifically require a 5w30?

Marauder was referring to Delo 400 LE 5W-40. The "LE" stands for "low emissions" and it is indeed a low SAPS oil (sulphated ash of 1.0). It currently sells for around $19 per gallon at my local Walmart. Rotella T6 5W-40 is also a low SAPS oil and sells for around $21 per gallon at the same Walmart.

If you don't need/want a synthetic and are able or willing to utilise a 15w40 grade (you didn't specify the application), both Delo 400 LE 15w40 and Rotella T 15w40 are also available at Walmart for significantly less (around $12 per gallon).

Finally, there is Rotella T5 10W-30, which is also low SAPS and sells for approximately $16 per gallon at Walmart.

I should note that all of these oils are dual-rated, and I've used both Rotella T 15w40 and Rotella T6 5W-40 in our Subarus, and couldn't be happier with them. I may give the Delo a try next time since it recently showed up at our Walmart and is priced a bit better than Rotella, while also being an excellent oil. However, depending on the time of year, I may move to the Rotella T5 10W-30 instead.

Unfortunately, vino_neuro is looking at HDEOs that are low phosphorous, more than simply low SAPS, thanks to his oil burning. Delo 400 LE 5w-40 is a competitor to Mobil Delvac 1 ESP 5w-40. The Delo 400 LE 5w30 is a competitor to the Delvac 1 LE 5w30, and are both at a substantially different price points than their 5w-40 counterparts. Of course, the 5w-40 examples have a much higher ZDDP content than the 5w30 variants he's looking at.
 
Thanks for the clarification.

Is there a specific reason to be looking at 5w30 in this situation? That was never specified in the original post, nor was the oil consumption issue, unless I've overlooked another thread where this was discussed.
 
I really can't speak for him, but I suspect it's because his vehicle was originally speced for a 30 grade and wishes to stay somewhat within the original viscosity specification. There was another thread on the issue, as I recall, but I'm not sure which subsection it was in.

He's looking for something pretty specific, and it's difficult to find, not to mention expensive. Low zinc, good anti-wear, 5w30, and a higher than normal HTHS (as opposed to a GF-5 5w30) isn't exactly easy to find.

If it were me, I'd probably do things a little differently, but there certainly is a method to what he's doing, and it makes sense. My first choice would be a HM oil or Defy. They don't all have very high ZDDP (some are SN/GF-5), but still might have a little more thickness. The Defy and MaxLife are purported to have a ZDDP that isn't going to be as hard on cats.

Nonetheless, I cannot pretend to have the answers. I'm sure his idea will work very well. It just won't be cheap.
 
Garak is exactly right, thanks for clarifying that. Low-phosphorous is what I'm after. The two oils I mentioned are very attractive because while they're low-phos, they are full-ash (I consider 1% ash standard level since CJ-4 is now the norm) and consequently have the robust TBN to handle our gasoline sulfut content which is still double that of what's in diesels.

I'm not married to the idea of using a 30wt, but all the low-P HDEO's seem to be. Some of the high-mileage oils might be good, but without OEM approvals it's anyone's guess how they perform. When you use a product like M1 ESP which is in your G37 that meets Mercedes 229.51, or a Delvac 1 LE that meets 228.51, you know that despite the lower phosphorous the anti-wear performance (along with oxidative stability, piston deposit resistance, etc etc) is still there that you'd get in something like M1 0W-40.

Alas, cost and the higher volatility (surprisingly) of these new HDEO's make them economically prohibitive.

Just put a dino CJ-4 10W30, LE 400 or Rotella or other, it is cheap and work well for normal OCI... No need for a 5W30 in 95% of use...

I am in Sweden, LAT 59° and use a dino 10w30 with no problem, pourpoint arround -35°, and Chicago is at 42° LAT

Hi Miniac, nice to se a swede as im a swede.
Anyway i´ve been using 10w-40 ci4 for years and my cat is still good despite the fact that my engine used gallons of this cat killing oils over the years.
- dont worry so much....the cat can take much more abuse than you think.
 
Hi neighbour,

I also use STOU 10w30 CF-4 in my volvo with no problem, but as vinu_neuro asked for low P oil, a CJ-4 10w30 will do the job for a good price, as it is available easyly in USA.

Never find a CI-4/CJ-4 10w30 at a good price in Sweden...

I don't recall if you mentioned in your other threads if you've tried to address the cause of consumption in the first place. Of course, if the vehicle is old and parts (and labour) are expensive, that can get prohibitive, too. And I'm assuming a cat delete in your state is out of the question. I suspect you have emissions checks there. This province does not.

The volatility of these lubes might be higher than we expect, but it's certainly within ACEA norms. While we all like a low NOACK, I don't think we need to get too concerned. As for availability and cost, that's going to take time. The Delo and the Delvac 1 LE are the only ones that I can think of that are close to what you need. You go to something like Petro-Canada's 0w-30 HDEO, and you wind up with way older API specifications and nothing on the ACEA or MB front. Any other 5w30 HDEOs I've seen are similarly dated.

I'd suggest a lubricant tailored for LPG or CNG, since some of those have had lower phosphorous. However, the TBN on them is dismally low, since fuel dilution is never an issue in those engines.

I wouldn't dismiss a HM oil too quickly, particularly if you can get a sensible one at a decent price. Their TBN isn't low, and considering you're going to be replenishing, I don't think you'll have problems. MaxLife and M1 HM at least claim some ACEA specifications. This is for the Prelude, correct?

And that's absolutely true. There are some considerations, though. Some places, like here, allow for a cat delete - at least the law is rather silent on it. If I burn out a cat, I replace it or I throw it out. It's up to me.

Others don't have that option or have regular emissions testing. And of course, it all depends on how high the consumption actually is and what the driving habits are like.
 
Yep, I've settled on Rotella 5W-40. Most people with consumption seem to be ok with the cat lasting. Couple days ago I read a Ford study from a couple years ago that found that cat poisoning is much worse from oil leaking past the valve seals than rings/pcv system. Mine is from the latter. I tried my best to be environmentally responsible with regards to the cat, but it didn't work out.

1qt/2-4k miles is the norm for this engine. T6 seems to have a good record of reducing oil consumption and hopefully it will for me. If the consumption goes down, the cat poisoning will reduce too. Other pro's are that it quickly shears to around a M1 0W-40 viscosity (which is horrible in oil consumption) which will help fuel economy. Being available at every Walmart for $21 a gallon certainly pushed it in the right direction.
 
That's quite sensible. All you can do is experiment, and see how things turn out. One quart per 2-4 thousand miles isn't too bad. I've seen much, much worse.

And don't be afraid to shop around. I was always under the impression that the Rotella was the cheapest synthetic HDEO around, given its widespread availability. Delvac 1 ESP is about half the price of either M1 TDT or Rotella synthetic here. However, that's a function of Walmart Canada's everyday gouging prices, and comparing prices at the oil companies' distributors would probably show them to be much, much closer.

You might be able to tell that I've been extremely peeved at Walmart lately.
