Re: Interesting Oil Info
 

As it were I just heard about this at work today. They sell an additive or there is an oil they use to break in cams etc that has all these heavy metals, its like $6 a quart.

Re: Interesting Oil Info
 

These EPA changes really suck; I believe this started taking effect a few years ago already. Now, without digging into it, aren't diesel oil except from these new regulations? If so, Delvac and Rotella are both very good oil choices.

Re: Interesting Oil Info
 

Merging thread with our current oil thread.

Re: Engine Oil
 

A lot of the Subaru guys swear by Rotella, maybe this is why I guess. I planned on running it in the WRX next oil change anyways since it is made especially for turbo applications.

Re: Engine Oil
 

From what I understand, some Rotella is SM rated also, meaning it's going to be in the same boat as others (no good).

If you can find an SL rated Rotella, then that will have a better additive package. Otherwise it sounds like looking at some of the other diesel oils, other then Rotella, is what some of those guys are doing, because a lot of the other ones don't seem to care about the SM rating so they keep the additives.

Just some interesting stuff I though.

Re: Engine Oil
 

^damn right interesting thanks.

Re: Engine Oil
 

Well I just went to Napa and checked out the oils. Everything passenger car related was SM rated. So I moved over to their diesel section. They didn't have Rotella. But they had Mobil, Delo, Valvoline, and Napa brand diesel oil. All of them were CJ4 rated, which per the second link, shows that it should have just over 1000ppm of Zinc and Phos, which is a good amount. I ended up picking up a jug of the Napa brand, and did an oil change. I guess I'm going to be shopping in the diesel oil section from now on.

Re: Engine Oil
 

Pardon my stupidity, but deisel oil isn't that special, is it? not "deisel specific" but rather, a different weight, like 15w40?

Re: Engine Oil
 

Different weights (15W-40 and 5W-40) and generally designed for more heavy-duty use and applications. I might have to switch the Evo over; I'll have to take a look at the synthetic varieties.

Re: Engine Oil
 

Brandon, what have you heard about the engine oils that are both SM & SL rated?

Re: Engine Oil
 

The SM/SL spec change is pretty stupid. In a quest to reduce the small-but-not-zero possibility that zinc/phos *might* hurt cat converters, the EPA has set up a loop that will cause a LOT of owners to change their oil more frequently.

The main reason for oil changes is to renew the additive package, not to get dirty oil out of the system. Modern oils and filters are pretty good at suspending and capturing any nasties that actually get into engine oil.

Since the new 'smaller' additive packages don't last as long, people are going to generate 5 liters of 'used' oil 2-3 more times a year. And since synthetic oils more than doubled in price over the past year (M1 at WalMart went from $20 a gallon to around $40- a gallon), it will cost people another $120 a year in oil. Minimum.

Yah, since getting a set of cats changed at a dealership will cost over $1000- the SL/SM change might seem like a good decision. But the chances of a cat or O2 sensor being wrecked by an oil additive package is under 5% over the life of any car (assuming 150 k miles on the car) and way below 1% for the fleet.

With a decent PCV system (including catch can) and decent engine maintenace, an owner can take the likelyhood of this problem from damned small to extremely low/zero.

Re: Engine Oil
 

The above info is dead-on accurate; most people just don't understand this and are convinced black oil = bad :(

A 5 quart jug of Mobil 1 is $26 at Walmart though (bought some this morning). As a sidenote, a few weeks ago my friend had his 8k mile old Mobil 1 from his Evo IX analyzed by Blackstone and it came back with enough additive package still remaining to be effective (3.1 TBN; anything >1.0 is satisfactory for use).

Re: Engine Oil
 

Rotella comes in 10w-40.

Re: Engine Oil
 

All Walmart had for Rotella today was 15W-40 conventional and 5W-40 synthetic.

I'm going to stick with Mobil 1 10W-30 since that is factory-fill for Evo's and all my car has ever seen.

Re: Engine Oil
 

You can also get Rotella in 10w-30.

Re: Engine Oil
 

Wow, back down to $26- a jug. I'm off to Wally-World. Did you happen to notice if they had any 5w-anything or was it all 10w and heavier?

Many thanks for the heads up......

Re: Engine Oil
 

I saw 5W-30 and 10W-30 at $26; there might be more weights, but I didn't look.

Re: Engine Oil
 

Mobil 1 5W-40 turbo diesel FTW. SL/SM with the higher levels of Zinc and whatnot. Plus you can get it at walmat in a jug for walmart prices.

Re: Engine Oil
 

I love information like this. I told someone that I had over 5k on my oil and they looked at me like I didn't care for my car.

Re: Engine Oil
 

I've always used Mobil 1 10w30 and never had an issue.

This Saturday I used Valvoline SynPower 5w30 synthetic (had it lying around) and Sunday I have rod knock.

Most likely a coincidence but I tell you what... I'm never using anything but Mobil1 10w30 and up again.

Re: Engine Oil
 

Yea prolly not from the oil, but Mobil 1 and Castrol syntec are what I use.

Audi just got fresh oil a couple weeks ago. Syntec 5w-40.

Re: Engine Oil
 

I change my oil filter every 3500 miles and change the oil itself at 10500 miles.

I suppose I could send a few samples off to Blackstone just for arguing rights. I have a full change coming up in 1000 miles.

First sample: 50 miles after a full change
2d and 3d samples: 50 miles after filter changes
4th sample: 50 miles before the next full change

Re: Engine Oil
 

Im using Shell Rotella 5w-40 synthetic and its working great. Keeps the lifters quiet and really looks decent after 3k with a Pure One filter. Im suprised that people didnt catch on to the diesel oil sooner. If it can handle a giant tractor turbo, my little evo 3 is a walk in the park. I have been using it for a year now and couldnt be happier.

Re: Engine Oil
 

I used nothing but Rotella on my old stock motor. But with the new motor I was using mainly synthetics. I had no reason to think oil quality has gone down until I read that article, which now has me back to using diesel oils.

Re: Engine Oil
 

Oh btw, stock oil change intervals on the Audi are 15K. I wont be doing that... probably twice a year regardless of miles. Maybe every 7k.

Re: Engine Oil
 

Go for the factory interval! Send a sample in after 6 months and see how its doing before changing it.

Re: Engine Oil
 

Rotella is all I used way back in the day with my white 1G Talon.

Re: Engine Oil
 

I would but leaving the filter in for 15k seems a bit risky? I dunno, just seems crazy. lol

Re: Engine Oil
 

Shouldn't be an issue as long as you're using a quality filter like the OEM one from the dealership. Does the A4 use the same canister style filter element that the Jetta GLI does? Those are known to last longer than your typical self-contained filters.

Re: Engine Oil
 

Yeah, the 2.0T's have the canister style on the side of the block if I remember.


15k?? Thats nuts! I ran Valvoline 10w30 in my laser up until recently. I switched to Valvoline full synthetic 10w30 and boy did it leak the oil. lol

Re: Engine Oil
 

Yea it has a stupid canister mounted at an angle... so when you take if off and dont have the special bleed tool for it, oil spills all over. Sweet design! lol

The M had a canister right on top of the engine. So much easier.

Re: Engine Oil
 

That was the best oil filter design I've ever seen.

Re: Engine Oil
 

Well, I picked up some Rotella 10w-30 that was CJ-4 rated, so it should be pretty good. And also a WIX filter, which according to a friend at O'Reilly's are the best ones they stock, after they took about 10 different brands and cut them apart to see which ones were the best.

Re: Engine Oil
 

^^ That's the same combo I run. It works pretty well!

Re: Engine Oil
 

Wix = OEM Mitsu = Napa Gold. It's all I run as well.

Re: Engine Oil
 

i dont understand why people dont run diesel oil more in turbo charged cars cause it has an additive to stop the soot from entering the oil and it has an additive to help with the lifters and everything. Deadeye Good choice on the oil. Rotella is some of the best out there. as long as you run a good filter like a mobil 1 or a purolator pure one you shouldnt really have an issue. synthetic oil is the way to go now of days cause when regular oil breaks down synthetic oil just starts to work. the choice is yours and yours alone but i would say rotella 5w40 synthetic and a pure one filter.

Re: Engine Oil
 

5w is pretty light isn't it? Why not 10w?

Re: Engine Oil
 

well i dont know alot of guys that start up the car and go making freeway pulls or race people while the engine is cold. 5w 40 is the synthetic oil that rotella makes. you can use this oil all winter long also. That is why i say 5w40

Re: Engine Oil
 

5W-40 is a year-round oil just like 10W-30 generally is. The reason the US uses 10W-30 instead is for better fuel economy. 5W-40 is fairly widely recommended outside North America instead of our 10W-30. Having close viscosity ratings is beneficial though for other reasons such as less chemicals/more oil and better sheer stability; everything has its pros and cons.

Re: Engine Oil
 

I ran into this test on another board, seemed informative enough to post here, especially considering it contradicts things I've been told by other members.
