185MM & Mobil-1 0w-40

[gt4awd]

A few weeks back my 02' C32 started to display "Engine Oil Level - Visit Workshop", and the electronic measurement will not work. Always displays "Perv. Serv. On Time". I haven't bought the shop tool dipstick yet, but do plan on getting it here soon. I've put around 8k on the previous oil change using Mobil-1 0w-40. When the message first appeared I had to assume the oil level was low being that I filled with 8 quarts even instead of 8.5 so I added a little less than half a quart. The fault message didn't go away. Wouldn't want to overfill so I did not add anymore oil. Mainly my question is this... Should I expect to be burning additional amounts of oil with the 185MM OD pulley? I would assume so especially considering the oil's weight. After some research, and opinions I've decided to go with Castrol Syntec 5w-40 as lab tests have proven is does provide more lubrication than Mobil-1 equivalent. I'm thinking the additional weight should also help if there is oil being burnt. Will also be using "Restore" to seal up any loss of compression within the cylinders. Anyone have positive, or negative experiences with "Restore"? It was advertised in my Superstreet magazine... C32 has 90k miles now.

Restore is garbage. Stick with M1 0w-40.

No experience with OTC crankcase elixirs or potions.

Successfully used Exxon Mobil's API SM-rated synthetic formulation with ~1200 and 1300 PPM of phosphorus & zinc, respectively. Barring external leakage, our long-block has proven able to cope with substantial additional boost sans undue oil consumption. Have yet to burn a even a liter between biannual change intervals after more than 81,000 sporty miles. UOA’s have thus far reported a clean bill of health...knock wood. If yours is failing, a leak-down test will best determine which components are due for refurbishment.

Incidentally, there’s no need to purchase MB’s workshop tool to ascertain its proper sump oil level.

Thanks for the information, and the PDF file splinter. I'm still unsure about "Restore", but their advertisement showed a compression test before, and after the use of restore on a higher mileage 100K engine that seemed very promising. Who knows if it does the job in reality though...

I believe it may be the oil level sensor has failed. I assume this being that the electronic measurement no longer works. This message showed up after completely disconnecting the ECU to work on my gauge setup, but I don't think it's related to pulling the ECU. There are no signs of oil leaking anywhere. I'm probably just thinking about it too much, but it seems the engine has a rough feel to it now. That's why I was worried about the possibility of the 185MM setup causing excessive oil burn.

The ‘perform service on time’ admonition typically displays when insufficient time has elapsed for the oil to return to the sump after shutdown, or when FSS-prescribed change interval’s have been exceeded. Probably not the case in your instance. Have you attempted a reading prior to a cold start or when in dyno mode?



Our oil level sender unit has been problematic for some.
Its superseded PN is 006 153 29 28; requires seal 024 997 70 48.

Several here have installed oversized crank pulleys and opted for a complementing tune. Have a look in the engine compartment while it’s running to help rule out possible pulley, idler or belt irregularities. The “rough feel” you’re currently experiencing is certainly not normal or owing to the oil’s level/quality being slightly off of specification.

[gt4awd]

Yes, I have waited the elapsed time which I believe the manual states at least five minutes? I've gone in excess of ten minutes, and get the same message. Attempting the measurement cold after vehicle has sat for long period same results. I have not tried the dyno mode method yet, but will do so after changing the oil tomorrow. The ECU was tuned for the 185MM directly through LET with their stage 2 ECU flash tune. No dyno tuning was done. No CEL indicating lean burn, or any other problems. No pending codes... I torqued the OD crank pulley to at least 180ft/lbs. No visible wobble. May have over-torqued the needswings PSK pulleys, and my supercharger pulley bearing is starting to go. Might be the bearing causing the additional slight vibration.

I had experienced the same issue. Around the time that the oil would need to be changed I would get the low oil message. It would come on and go away on its own. I checked it a couple of times and it told me that the service was on time. I had noticed that it would occur if I was on uneven surface. I finally got a reading saying that I needed to add a quart. Apparently if it's less than a quart, you will get the service is on time. I only got the low oil message when I was driving.

Does this occur all the time or after an extended amount of time after your oil change?

[gt4awd]

The message just recently showed up, but it was after 8,000 miles since last oil change. Bought this C32 nearly five months ago, and did the oil change at 83k miles. The oil fault shows around 30 seconds after putting in the key, and turning to position two. I don't have to start the engine for the message to display. After changing the oil today it again displayed as usual. Wasn't able to run the engine much at all though, because of the power steering leak.

When I first bought the car I thought it was a sign that I need to change my oil because I was waiting for the normal interval to change the oil. I would say change your oil and see if goes away. I think it has to do with how many miles you have on that oil change.

There are just a few quarks to the car, I'm sure you'll get every thing resolved.

Off the top of head I thought, "Restore is crap", but rather than jump to conclusions, I visited their webpage. This quote is from their site:

How does RESTORE work?
RESTORE is the only product that contains the technologically advanced CSL formulation which actually fills in and seals microscopic leaks in the cylinder wall. The result is increased engine compression and more engine power.

The first question that came to mind was – if this *product* "fills in and seals microscopic leaks in the cylinder wall", shouldn’t the oil filter, which has a bunch of small holes, be a solid mass of restore after the first few miles? When that happens, shouldn't the oil pressure drop to zero? If the answer is: "Restore somehow knows the difference between a filter and metal", there’s a couple of follow up questions.

How does it know not to completely seal the valve guides? If that happens, wont the valves wear out in no time due to a lack of oil?

I have the rocker shaft to bushing clearance specs for a 2.4 liter 911 . It's 0.00065" to 0.0014". Same problem there. It's tight, and if Restore does what it claims, it would cement the rocker to the shaft. Restore would have to somehow differentiate "some metals" from "other metals". I think that is unlikely.

Just in case you think I'm jaded, Avco Lycoming is a major manufacturer of aircraft engines. They were interviewed for an oil additive article and said, "We have tried every additive we could find on the market, and they are all worthless."

I can list several other non-biased sources who have been quoted as saying the same thing.

In the end, it’s your engine and you should do what you think is best. Lastly, here's a little information on the M113's cylinders.

I did the oil change, and ended up adding the restore. So I guess we will soon know if my engine dies out. I'll make sure to check the filter after thirty minutes or so of running the engine, and occasionally beyond that point. It does state on their website that restore will not damage the engine, and was used in over 25 million engines without damage.

[TemjinX2]

well let us know. i know in the honda world its a hit or miss. Some people swear about it, others say it didn't go anything.

[gt4awd]

If it doesn't do anything I'll be fine with that. If it appears to be clogging the filter I don't think that's a good sign. With it being used in such a mass amount of vehicles I doubt it will clog the valve guides or anything. It is diluted into nearly 8 quarts of oil, and is a half quart can. I believe the solution only fills microscopic abrasions. So clogging shouldn't be an issue. Can't do anything though until I fix the power steering pump.

[MarcusF]

I doubt it will do anything. I just find their claims laughable.
"it fills in cylinder walls" How would the stuff know when to stop filling in?

If the product did what they claimed, no one whose engine had honed cylinders could use it.

Restore stays in business because a sucker is born every minute.

Good Info !
