I am wondering if anyone has used 0 20 or 0 30 synthetic in their tl type s...mine is a 2007. Anyone see the benefit of using synthetics or is fossil oil good enough? Just wondering what the experiences are. I have a Saab 9000 Aero with 200k miles on original turbo using synth. I have a friend who raves about Amsoil and amsoil filters; he did an oil analysis, engineer, and found he can go 15k between changes in an M3. I'd rather not spend 9 a quart,but that length of time with changes is very attractive to me...
thanks in advance

There have been millions of posts on oil, but as I'm looking for houses on the 'net and have some time, thought I'd reply:
Use regular Dino 5-20 oil and change when recommended by the MID and you'll never have any problems.
I believe BMW recommends 15K oil changes when their oil is used, but not so with Acura.
Hey, you could get the Amsoil 0-20 and change it every 25,000 miles if you want, which is their recommendation for normal service.
Everybody raves about their own oil preference. Our RX7 Turbo has lived on Rotella 15-40 and no problems.
How many engine failures have you heard of that have been oil related?

The choice is yours.

Thanks. I was just wondering if it is worth the cost, and if anyone has had experience running synth for lonber mileages. I have always changed my Castrol Syntec at 4-5000 miles and have had great luck.
Has anyone noticed more mpg from Synthetic?

Most BMWs hold twice as much oil as the TL, that's part of the reason for the long OCI.

Where do you live? There are very few places that require a 0w or 5w oil. I like to stick with a good 10w-30 since it's more robust and sheer stable than a comprable 0w-30 or 5w-30. Where I live, it hardly ever gets down to freezing.

Anything will work fine in the TL. Don't lose sleep over which oil you use. Keep in mind with the long OCI, the oil may be in good shape but you still have the contaminate load that needs to be dumped.

@op - consult your manual: 5W-20 is the recommended weight for your vehicle. Synthetics are fine, but not required.

5-20 is fine but not necessarily the best for lowest wear.

It's a push from CAFE, nothing more.

Its also uses German Castrol which is a top tier group IV synthetic. My 330's MID looks for an oil/filter change every 15K miles.

I used 5-50 in my Saab Aero for 200k miles. Castrol syntec. I was surprised the TL type S used 5-20 per the manual. I was aware of that and thought the 0-20 or 0-30 might give a bit better high or low temp. We do get sub zero weather but my car is garaged. Anyone used Amsoil oil or oil filters. My buddy says they are rated much much better than stock oil filters and the oil is supposed to be great? Like royal purple or Redline I guess?

Really just want good protection and thinking synth might yield a bit better mileage

The 20wts are more of a CAFE push than anything.

Amsoil makes great oil and even better filters. The EAO line of filters will go 60,000 miles with better flow and filtration than the others. They use the Donaldson synthetic filter media and package it for passenger car use.

I've seen enough independent studies on their filters that I run them through 5 intervals (25,000 mi) before changing them.

Many oils to choose from all the way from a good grp III to a full IV/V synthetic. I run their straight synthetic 30wt in my TL.

The truth of the matter is that unless you plan on keeping the car forever you will probably never see the advantage of the synthetics unless you're going for a longer drain interval as you say.

I'm OCD and I plan on keeping my car forever so I buy the good stuff and go no longer than 5K miles on it.

If you plan on running a 20wt, Redline makes the best 5w-20 around.

Amsoil's 0w20 is a step up from their 5 or 10w30 which are great oils. The above post is correct in describing their filters. I run the 0w20 in my TL and change oil and filter every 15k or one year which ever comes first.
(The 15k comes first!)
I live where it is damn cold so the synthetic offers me better protection at start up. The other good thing about extended oils drains is it puts less dirty oil in the environment. Using Amsoil as directed if cheaper than running conventional oil. Better protection for less money and less harm to the world. How can you go wrong!

In which way?

Tripnbeats

i used it once....ill never use it again i didnt like how the car ran after the oil started to break down. ill stick to what acura says to use 5w20

I hate cars

What oil?

Keep in mind these engines are still spec'd for 30wt and 40wt oil in other parts of the world where CAFE isn't around.

0w-30 or 20 i dont remember i was in fl like 2 yrs ago and saw it... mobil 1 so i was like hey look it says great replacement for 5-20 motors.... so i put it in it was time for a change anyway and i drove back up to NY and i didnt like it... just felt like the motor was taking a heavier beating

The zero w oils are a step up in technology. The reason syntheitc oils are better than conventional oils is simple. They are able to put in more additives in sythetic than base oils. Additives take care of problems like moisture in your oil and so on. I will try to find a link to a publication called the motor oil bible. It is way more information than any one really needs to know about oil but it is intersting. I will post the link back here if I can find one.
Amsoil is the only manufacturer that says," if you have a lubrication related problem with your engine while using Amsoil as directed, we will fix it at no charge!"

tech_rcd

Here is the link I mentioned. It used to be free but now I see he is charging for it. You can still look at some of it for free. Enjoy reading what you can.

Synthetics, among their other advantages, allow the use of less VIIs due to their naturally high VI. Less VIIs means less sheer both temporary and permanent.

I like synthetics. They flow better cold- you can see this right out of the bottle, comparing weight for weight against conventional.
I use Mobil 1 5W-20, and let the MID tell me when to change. That ends up being around 6000 miles. I would go a bit longer, but I'm only driving 6-700 miles/month, tops, so the changes are 8-10 months in between.

Why Mobil1? It's easy to find.

Oh, and as noted- BMW does really long intervals for a couple of reasons-

1. They have giant oil pans in comparisons to US and Japanese cars. 7 quart fills.
2. The German govt has "persuasively" suggested that BMW reduce their fluid waste streams on their cars. Not that it's necessarily the best idea for long, long engine life, but it looks better on paper. Read up on it on their corporate website.

yea my friend picked up a 335 I and put 9 qts in at change after 12000miles....unreal....I dont understand how that can make the engine last so long the dude beats the piss out of it everyday

I was thinking about putting Royal Purple in my TL. I looked at diff oils at Autozone and tried to find this group III, IV,V rating. Where is it? I also living in Northern IL where its VERY cold in the winter would think Synthetic would be MUCH better due to the thin Viscosity at VERY low temps.

What should I use then? Royal Purple, Redline, Amsoil ??? Which one, not sure where to look for the top group rating???
