Read our primer articles on High Mileage Oil, Synthetic Oil and Kinematic Viscosity

It's near time for the 8k mile oil change for the car in my sig.

There are three things I look for in an oil.

1: API rating. It has to have the starburst on the container. If it does not have it, then I don't look any further.

2: ACEA rating. It has to have a HTHS of at least 3.5. So that means it has to be A3 or better. I've read that you can go to a higher A rating, but not lower. So if it's A1, it's rejected.

3: MFG approval. A great deal of money is spent on R&D to make sure the oil can handle the engine. Auto makers work closely with oil companies on that point. BMW works with Castrol, as does Audi/VW though other companies will pony up the money to test their oils. It's the same with Porsche/Mobil, Ferrari/Shell, etc.

Other companies also work with the auto makers. BMW factory fills with Castrol, but Valvoline/Mobil/Pennzoil also have BMW approvals for some of their oil. Porsche has over 100 approved oils, but factory fill with Mobil 1.

My point? Engine makers know more about their engines than anyone. So I'm a big proponent of using mfg approved oil in my engine.

So it is LL-01 for me. It is a point that I can bend on a little though, as my 6yr/100k mile warranty is up.


The next post will be a list of oils I'm looking at, and finally, the one that is my choice.

Feel free to advise, but within the paramaters. (LL-01 isn't an absolute.)

In no paticular order:
Motul 8100 X-MAX 5W-30
http://matrixsyntheticoils.com...0%20x-max%205w30.pdf

Castrol Syntec SAE 0W-30 European Formula (Meets all the specs.)

Castrol Syntec SAE 5W-40 European Formula (Ll-98 instead of 01 but meets the other two.)

Liqui Moly Leichtlauf Special LL 5W-30 (meets all)

Mobil 1 0w-40 (Meets all) The flagship as far as I'm concerned. Can't argue with Aston Martin, Porsche, Mercedes AMG either. My favorite oil.

Pento High Performance 5W-30 (Meets all)

Pennzoil Ultra 5W-40 Euro (I understand Pennzoil is going to set a link on their site so we can buy it. It's hard to find.)

Q HorsePower SAE 5W-40 (as of 2007 LL-01 approval was pending)

I know one who ran uses Motul in his M3 and is happy with it. It is also expensive compared to the M1.

Note the timing gears from the 2.5 Boxster M96 engine. 0-40 M1 with excessive oil change interval. It was specified by the factory. Government regs have a great deal to do with current oil specs. Any of the products you have listed for consideration will be OK BUT chose an interval that suits the one you choose. Error on the side of caution. Any of the synthetic products listed are overkill,especially if the change interval is shortened. I treat my toys better than I have to,so no lecture here about spending more than you have to. DO WHAT YOU LIKE. You must have some opinion about what you do and dont want.
Castrol Syntec SAE 0W-30 European Formula (Meets all the specs.) That would be my choice, seems to be a favorite oil for many drivers, with tons of data backing it up. Save the thicker stuff for if/when you ever have oil use problems. The other nice thing about the Castrol product is it is pretty easy to get, no jumping through hoops.

I have a few Shipmates using Castrol in BMW and they're all happy with it, engines are staying clean. We had the VC off one at the Hobby Shack not long ago, 100,000+ on the clock and clean as a bell using GC 0W30.

My OCI is normally @8K miles. Even under warranty I changed it halfway through. (I treat my toys better than I have to as well Smile)

I do have an opinion, thus the parameters I mentioned. But feel free to offer your advice. I may not heed it, but I won't bite your head off.

FWIW, I burn a qt /6k miles.

GC is a very good oil. I've used it a few times. The factory fill is rebadged Castrol TXT 5w-30.

There is one oil I didn't mention, though I'm using it. Mobil 1 TDT 5w-40.

Miscommunication between myself and my mechanic led to that. My fault that was. I wanted the Pz-5w-40, but the distributor didn't have it listed. (Common as we've heard over at BITOG). So I said "The M1 then.", meaning the 0w-40. Oops.....

Anyway, I looked up the specs, and was really surprised at the HTHS of 3.9, which is a tad higher the their 0w-40.
Trajan, what type of driving do you do, I remember corresponding with a member on BITOG about a particular 0W-20 motor oil that was rated for 25,000 miles or 1 year under normal service and 15,000 miles or one year under sever service, he asked me how many miles I drove the car a day, I said 20 miles to work and 20 miles back home, he recommended a 7500 mile OCI.

So, with what he told me, I am using PP 5W-20 and doing 5000 mile OCI's.

This person was a member of Terry Dyson's Blog, and he did not try to push Biosyn on me.
Im hesitant to recommend any product that I dont use myself or have any experience with. I can tell you the I use DELVAC 1 5-40 and lubrication engineers monolec SPB 5-30 in my own cars and trucks with no complaints. I also use lucas pure synthetic additive in some applications.Ive found it to be A very different product than their standard gorilla snot stabilizer. All depends on application and usage.

I came across this here: http://forums.bimmerforums.com...wthread.php?t=265292

"A note concerning Mobil 1 5w-40 SUV oil. I know that somebody is going to go to buy this and say "hey it doesn't say ACEA A3 on the back." They are correct. The 5w-40 oil repackaged Mobil Delvac 1, a Synthetic Heavy Duty Engine oil originally designed for trucks and fleet vehicles. This oil is slightly heavier than the 0w-40 and has an HTHS of 4.1. It meets ACEA E3,4 & 5 which are diesal requirements but still require an HTHS of greater than 3.5."

If it's the same as yours, that would be a good choice. I favor the higher HTHS numbers myself.

I hesitate to recommend oils I don't use too. In general though, I think an ACEA A3 oil is stouter than an non rated one of the same weight. JMHO though.

It's a car built for high speed/high rpm driving all day Smile

But seriously now. Most of my driving is highway. I'm about 1/2 mile or less from an expressway. Usually shift @2-2.5k, but once in awhile I rip it to 6k or do the Itailian tuneup.

No track days. But I average about 20K miles a year. (Bought it 4/06 with 10,300 miles, just turned 113,000 today.)

Since you do Highway Driving, I am guessing your driving at least 30 miles or so one way, and about 30 miles back, regardless of how many miles you drive on the highway, this is not stop and go driving, so 8000 mile OCI's should be fine.

If this car were seeing mostly stop and go driving or short trips then I would be more concerned with the oil choice. JMO
Trajan,
Might look at Royal Purple 0w-40. API certified, meets A3 specs.

My mechanic just filled my Titan's sump with 2qt's RP break-in, and the rest 5w-30. He just installed my JWT cams and springs. I will run it for 1K then dump.

Eneos is getting some good reviews, although it's TBN is a little low, but supposedly, it retains it longer.

If not, run GC. I just bought a few qt's (all they had at A.Z.), for my OPE. If the truck does not like RP, I am going to use GC.

Have a good weekend, I am headed to Crystal River tomorrow for some scalloping over the long weekend.
Dave
The only thing with RP, is they keep the HTHS a secret, but if the 0W-40 meets A3 spec., It would be a good bet it will meet LL-01. I have started using Synthetics in just about everything now, although Dino's are just about as good. The Wife's Altima is filled with PYB for a 3000 OCI (because I received a few jugs from a friend). She does a lot of short trips. Next OCI will be PP or PU.

I have not been scalloping in a few years, so should be fun. My Sister decided not to sell her 330Ci, so I am using some of my saved money for me and the Wife. She is getting new rims and tires for the Altima, I got cams and headers for the Titan.

Dave
The LL-01 is a different spec then A3. You get one free oil change per year or 15,000 miles, which ever comes first, so they have that spec.

http://sas-origin.onstreammedi...009/RP/PC/index.html

Now that I'm out of warranty, I can bend on the LL spec. But if I do decide to go 10k between changes, then I'd lean towards it.

But still, the RP is a viable choice. Nice to have a boatload of good oil to choose from.

There are quite a few quality, off the shelf oils that will meet your needs.

The RP seems to keep my Titan happy, although I have only had it in for 200 miles. I don't know if the extra cost is worth it, as platinum works as good in the VK56DE.

Dave


It is a requirement, but if you look at the link and compare the two (ACEA A3 with BMW LL-01), you'll see a bit of difference.

Kind of like how all poodles are dogs, but not all dogs are poodles. (M1 High Mileage 10w-40 is ACEA A3, but not LL-01, for example.)

One reason I started this was to look for and discuss a viable alternative/s. I didn't know RP made a 0w-40.

Thanks to you, now I know of another worthy oil Smile

BTW, the 5w-30 and 40 is only A-2. The 0w-40 is A3.

Dave


Eyes bleed and head spin. Probably why it's just so much easier to look at BMWNA's list. They did all the work for me.

But what would be the fun it that? (HEHE)
