Oil Recommendations for engine bout to hit 100k

[djs]

look, im not trying to steal this guys thread, nor am i trying to get into a mine is better than yours debate i run M1 in my car because i have run it in other vehicles in the past with great success.

Agreed. That was not my intention, just trying to continue the debate and add to the thread.

... but if i were on the road somewhere id like to be able to get it off the shelf... .

Agree again...ELF is not readily available and you have to go looking for it. I was in a pinch with my wifes Avant recently and had to go off the shelf and honestly for the single quart that I bought, I don't even remember the brand at this point.

... i hope M1 is not French, im going to have to go look later...

You have to admit that if it is, that would be ironically hillarious!

[EErie B6]

i have a few comments that id like to add, but i have to wait till i have more time. busy, busy, busy. hopefully this evening ill have time.

[ttay1977]

I also heard M1 isn't what it used to be. I'm not sure what that means and can't speak to it technically, but I've been really happy with ELF thus far, performance for the cost can't be beat in my mind.

M1 used to be a group IV based oil ("true" synthetic) and is now group III - highly refined dino juice like Castro and most other "synthetics" on the market.

[setay]

i personally stay away from castrol, being that castrol is owned by Better Petroleum (BP). BP also owns Arco and we all know Arco = Fail, so with that, my logic suggests Castrol = Fail. just my thoughts

[GO-GOTEKNO]

I started using royal purple and love it as for filter go with Mahle oversized

My mechanic suggested ELF because it was a good "cleaning" oil.

A good "cleaning" oil simply means that it has a high detergent content. Any good reputable oil should have this... M1, Syntec, Penn. Plat., Royal Purple, ELF, Amsoil, etc. all of the so called "good" oils.

I also have a friend that runs it in his B5 and after a few oil changes and 10k miles, he's running a full "tick" lower on his oil temp guage.

ELF is no doubt a good oil, and the fact that he runs noticeably cooler is impressive... not sure how he judged that for sure, our B5 varies by as much as 50 degrees depending on the driving condition. also, going from old to new oil no doubt gave the ELF a slight advantage. still, its impressive. My Father's B5.5 Passat 1.8T often reads as much as 3mpg better on the highway after an oil change... and he uses 5k intervals like alot other 1.8Ters do


From what i have been told, any name brand oil, changed at a safe interval, when used with a good filter, should keep your engine clean & wear to a minimum... as long as you pick a safe weight for your climate.

P.S. after doing some more reading, i think that i had Syntec on a bit of a pedestal... and i think "setay" summed it up well in his post... i dont believe it is as good as i originally had it pegged.... its not bad, but there definately is better out there.

[A4TL]

castrol is used in the dinan 335 only requires changing about every 12-15K miles. even the oil cap says castrol on it. not sure what kind because they only sell the bmw branded kinda and if it goes low you just pop in and they give you a free bottle(you know the free service).

I'd like to fiind out this superman oil because the 07 335i had no oil cooler and 280-310 oil temps were easy. my 08 has a massive smoc (?) and it gets up to 275-285 max on a 94F hotlapping around the 'hood :)

Clearly no mortal oil can handle those temps so i am not sue what is up. you'd think after 15K miles you'd have totally trashed oil by getting it that hot (or your motor).

I'll wonder if anyone here can find out. I'd like to think if its so severe duty it might be nice to use in the audi. christ i thought synthethic sheared at 275F.. maybe thats dino oil i got mixed up?

[gdawg'05a4]

IIRC, even the newer Audis now says "castrol" on the oil cap now.

I've had no issues running German Castrol 0w-30 which iirc is factory fill.

[3ohAvant]

the only BMW castrol that I know of is the castrol tws 10w-60, its what is used in theie M motors. like the e46M3. This engine shears oils so fast that within 500 miles this 10-60 is like a 20-50. This oil is very hard to find. Typically only at dealers, and its $$$

[Monkey77]

So what is the end result on the ideal oil type for 100k motors?
any feedback?

[initiala4]

Elf or Motul

[fitch303]

Holy super batman back from the dead!!

So last oil change I used castrol syntec european formula 0w-40or30 don't remember but it was audi/vw approved. fast forward to today, I was in a hurry and grabbed castrol syntec Full synthetic 5w-30 but it doesn't have the vw 502 00, 505 01 marking in the back. I noticed the 0w seamed to burn off too fast and wanted to try something new, will I be ok using it?

Listed here, last listing at the bottom 5 1/2 quarts

best oil for daily driving i've ever used. i actually push it to 13,000-15,000 mile changes with use of mobil 1 oil filter. this actually equates to 2-3 month oil changes for me. i have been on mobil 1 extended performance for around 80k miles and have been on APR 1+ for 120k miles, now totaling 175k. no sludge, the valve train under the valve cover is spotless and with no stains. even when pushed to 15,000 miles the viscosity of my oil has not faltered and still retains the consistency of when freshly poured. i would imagine that if filtered this oil could be reused for another 5k miles no doubt. what you need in a good oil is an oil that does not break down due to heat and abuse. mobil 1 extended oil is the ONLY oil i have used that kept is viscosity after 15,000. even when other 15k miles lost their viscosity. Viscosity will allow your oil to provide the "cushion" needed to protect from metal to metal contact and any oil that when put through heat and abuse still retains its consistency will protect your motor.

for race use i personally love NEO Synthetics. if your budget permits race use NEO, ELF, and Motul are all good oils, but these oils don't support extended usage intervals.

[a4wheelin]

I just bought a 5qt jug of Mobile1 Clean 5000 5w30 at Walmart for $11! I've never used this oil before but the low price caught my eye.
From the website, "With all Mobil Clean 5000s, you will get 16 percent more cleaning agent than our conventional oil, Mobil Clean (available only at installed facilities)".

[fitch303]

^^^yeah but it's conventional oil, not synthetic. I used to use mobile synthetic until I saw a graph that shows how quickly it breaks down compared to others.

Oh shit really??? I thought all M1 oil was synth?

[a4wheelin]

Ahhh it doesn't say M1 it just says Mobil. That sucks I just wasted $11. :(

[widgget]

i use Mobil1 Synthetic 0W40

[jbrown7815]

i use Mobil1 Synthetic 0W40

same

[fritzner]

i've been using LubroMoly 5W-40 with larger OEM filters on 5k intervals for my last 4 cars over the past 9 years with no issues..



[side note/thread jack:
i just ordered oil and got the wrong stuff..

i wanted 5W-40 LubroMoly (LM2040) for my '05 A4 1.8T and my '04 A6 3.0L,


but i received 5W-40 LubroMoly Diesel High Tech (LM2022)..



is that ok to use, or am i S.O.L??..

i really appreciate any guidance..]

[fritzner]

Approved Oil List

ok, i found the LubroMoly 5W-40 Diesel is on the Approved Oil List..

now what is the difference between the Diesel and the regular purple jug -- they're both 5W-40 and both on the approved list..

so i guess i am good to run it this time??..

[FORCE_FED_DUB]

the main difference between diesel and gas oils of the same make are the detergents. i have run diesel oil before and it's not noticeably different, if anything it probably cleaned out the crankcase more. I'm not into boutique oils. M1 or Castrol full synthetic in either 0-40, 5-40, or 10-40. car doesn't seem to care as long as it gets changed.

I used castrol 0w-40 full synthetic and decided against this time around as I noticed my engine would drink the 0w like a mofo. What does the second number refer to? and why is the european formula only in 0w for castrol?

second number is shear strength. i have 10-40 in it right now, will be going back to 0-40 M1 for winter here soon.

[a4wheelin]

second number is shear strength. i have 10-40 in it right now, will be going back to 0-40 M1 for winter here soon.

2nd number is shear strength? So the higher the number the more shear strength the oil has? Is there a big difference between -30 and -40?

[UGwagen]

second number is shear strength. i have 10-40 in it right now, will be going back to 0-40 M1 for winter here soon.

wrong. 10w40 translates to properties of oil weight at cold & hot.

Shear strength has nothing to do with it. IN fact, shear strength varies with the oil & additive package, within a brand & competitors.

Mobil 1 0w40 isn't exactly known to be shear stable, compared to other Xw40 oils.

[BOPOH]

interesting, so using 0w-20 is pretty bad i guess?
what's the ideal oil for winter with average of 32F?

[bode]

so only one guy uses Royal Purple? This was popular in E36 BMW's. e46's had to use the dealer stuff. I HEARD that Royal Purple is the only oil that is fully 100% synthetic. I think Mobil one (or maybe it was castorol?) is close, but not 100%. I have been using Royal Purple on my BMW for years and loved it.

The term "synthetic" is so diluted, that it is meaningless now. If Royal purple isn't really willing to tell you what basestocks it uses (Group III, Group IV, & Group V)... for all intensive purposes it could be like most Castrol Syntec products and consist of Group III basestock.

[fitch303]

I just returned the oil and picked up the castrol synthetic european formula 0w-30 which has the vw 502 certifiction and an extra large mobile 1 filter for 30 bones at autozone.

[03a4sport]

Lubro Moly 5w-40.

[a4wheelin]

I returned the Mobil Clean 5000 that I bought accidentally and picked up a jug of Mobil 1 5w30. They didn't have any 0w40 or 5w40 so I opted for the 5w30. Nothing wrong with 5w30 is there?

[3ohAvant]

second number is the viscosity at temp. nothing to do w/ shear strength.

0-30, 5-30, 0-40, 5-40 all are fine. I'd stick with a 40 in the 1.8t, esp if modded. and the 30 in a 3.0.

0-20 is way too thin. prob won't protect the engine enough. this would also NOT be found on the VAG approved oils list.

many of the above oils are NOT approved on the VAG list. the only M1 is the 0-40. But that one is known to shear like crazy, and it ticks, and is consumed. after a few thousand miles, its like a 10-30.

stick with any of the approved oils, except for M1, and you'll be just fine!

[UGwagen]

if you want really good oils, forget about VW502.00 and head straight to synthetic heavy duty diesel oils.

You can easily find at wally world:
Mobil 1 Turbo Diesel Truck 5w40
Shell Rotella-T synthetic 5w40

both are excellent oils, with the M1 TDT being better (it will last longer than the shell)

A gallon of the Shell is $20 at Wally world.

[MikeWire]

I bought my Avant with 102K and changed the oil 3 times. First was with Pentosin, and now I'm at 118K with the last two oil (and filter) changes being Royal Purple. This next change I'll probably just change the filter and top it off, and start doing a full oil change every other oil change. I noticed on this last change the oil was still really clean, even after 5K.

FWIW I ran RP in my 2.0 MKIV for a long time and it had almost 140K when I sold it. My cousin has it now, and it's still running strong!

[A4SoftWalker]

you know german car motors are bulletproof. its the rest of the car (electronics,etc) that fall apart at about 100k :)

Don't jinx us lol 109k and counting Royal Purple10w-40+ Amsoil5w-40 50-50mix






According to Amsoil:::here their synthetic works for gas or diesel vehicles.

[dougyfresh]

I use TOTAL Quartz INEO MC3 5W30 in my car. Meets VAG requirements for our vehicle(s).

What are you doing with your audi, taking it through the Baja 1000. The heavy duty diesel oil is great stuff n' all and I'd run in it anything that I took off-roading, but there's no need for it in a car engine. You definitely could if you wanted to but I see no need for it. A good 10w-40 synthetic or 0w-40 synthetic for the winter off the approved list is fine. I don't know what the pricing difference is though.
