Any doubts about 10,000 miles on various M1 products?

[Jay]

My Acura RSX has the K20A3 engine with 10,000 mi as the normal service interval recommendation. I'm a severe-service driver with about 75% city miles, so my question was much like yours, S2000driver.

Oil analysis results (three of them @ 7,000 mi)have told me that 10,000 mi is very reasonable for M1 0w-20 and 5w30. I change at about 9,000 miles just to be safe.

Amsoil has TBN booster. It's called 'change the oil filter and top off with new oil'.

Unfortunately, your question leaves so many variables open that it is like asking, "if it is 40 degrees outside, will I be cold?" It depends on your driving style and operating conditions. If your cars are only driven on trips of 2 miles in cold weather and you drive 5,000 miles a year, 10,000 mile oil changes are to long. If you only drive your cars 50 miles each way to work and home, with no traffic on the freeway, then 10,000 miles is no problem. You have to look at the individual conditions, longer trips, more freeway driving, longer oil change interval.

Sounds overly ambitious to me; no way it would make it with me driving. Just check the level often. I find M1 (5w30) burned off pretty quick in my Integra; say 1L every 2000km or so. Why do you care about using 'recommended viscosities' if you aren't going to follow recommended OCI's? Personally, I think there's better stuff out there if you're aiming for 10,000 mi. OCI's. Just a thought.

There is no doubt in my mind that you could run mobil 1 at 10K intervals. I would do a filter change at 5-6K just to be sure.

Regarding the Mercedes comment....I have the exact same experience. Local dealer says they use M-1 5-30 in "all Mercedes".

You are correct, neither one is approved. Why are they being used? Because most dealers are RETARDS.

Sorry but your dealer is wrong. In order for an oil to be MB 229.1, 229.3, or 229.5 approved, it must have an HTHS of 3.5 or greater. The only Mobil 1 products that meet this are the 0w-40 and the 15w-50. Only the 0w-40 is listed by Mobil as being 229.3 or 229.5 approved. Also, Mercedes does not recommend a flat 10,000 mile oil interval, but instead uses an oil change sensor that recommends changes based on usage. Mercedes has been doing this since the mid-late 1990's. Finally, recommending 10w-30 carte blanc, is like recommending that everyone run Interco Super Swamper tires on their cars and trucks. While super swampers work great in muck on a truck, they would suck on a track car.

2 things...

1. the 0-40 in not readily available in Canada...and dealers figure they're all the same. After all, what's the difference between a 30 and 40 weight? Right?

2. I don't know about the rest of you guys with the FSS, but I can predict when my BWM will require an OCI within 1-200 mi. based on mileage. More frequent short trips/cold starts and it's 1-300mi. shorter of an interval, and a lot of highway will increase things by 1-300mi.. It has never differed by more than 500 mi. as far as I can tell...it's always 9-9.5k. Is that extra 500mi a big deal?

I would have a problem with a company that let's their dealer's run out of control. Maybe they know a bit more about local driving conditions??

The question is will they warranty this.

 

[williar]

Dr T, you might try GC 0w30; it's reported to be on the heavy side of the 30wt scale and shear-stable. As far as the FSS goes, the 300-miles spread indicates to me that it's not very accurate. However, I'd think that when running long-life oils (BMW LL-01) you should be good for 10K miles under almost all circumstances.

I'm in the midst of the Auto-RX rinse cycle. Once this is complete I will be putting M1 in the crankcase with a maintenace dose of ARx for a 10K run. I'll post UOA sometime in August-September. I'm sure M1 will perform well.

 

[Dr. T]

Yeah, I just put in the BMW 0W-40...figure I'd try the real McCoy first.

 

[haley10]

Dr. T, I looked briefly and it appears that no M1 w/SS has Mercedes approval for newer vehicles. 10W-30 was approved for certain previous models.

My M1 bottles in 10W-30 has no Mercedes approvals listed and it doesn't meet A3, B3, etc.

Valve train noise was sited on the MB approved list I looked at. M1 30 wts. were "specifically" not approved.

 

[S2000driver]

As I look around, it seems like 7,500 miles on full Synthetic is more comfortable to most people than 10,000 miles.

Hi,
S2000Driver - surely it is not what others on here feel "comfortable" with. It is as you originally "suggested", a fairly clinical decision you will make based on the UOA's YOU SHOULD MAKE. This is a sound and sensible way to determine a OCI

A UOA at about 7k should provide you with the data needed to go to 10k - or not!

As well, a UOA at the change point will confirm your decision. You may well be able to go further on M1 as proven by the 3MP project

Regards
