Hello,

I just took delivery of a 99 S320 with 12,411 original miles---What oil would you experienced W140 owners recommend? (synthetic or natural, and does brand make a difference?).

Thanks!

well synthetic is always the best, but it all depends if your pocket holds that, natural aint bad either like castrol gtx anti sludge protection its up ther $4.20 per quart. for the oil weight you got to look in th owners manual at technical refrence page, if i recall it right i think its 10w40 seasonal year round..

btw out of curiosity how much did you pay for the car ?? any pics of it ??

Mobil 1 with a weight that is right for your climate is what MB recommends for the W140.

Yes, typically whatever MB recommends is the best way to go, can't go wrong there. I think, it being a '99, technically they would recommend synthetic, however I've been told by several good mechanics that even regular oil is made well enough now that it works just as well, and synthetic is a waste of money.

Not sure how you feel about it, if you can afford it, may as well go synthetic (for the peice of mind), but if you're interested in saving about ~$60 or so per oil change, regular should be OK.

Check with an MB dealer for exacts, and somewhere there's a chart you can read from which shows what weights are good for which climates. Just remember good maintence and regular changes and you should get MANY more miles from your car. I've got over 140k now on my S320 and no leaks, no burning, still runs smooth! Personally, in the Wisconsin climate I've been running Mobile-1 10W30 year-round and no troubles at all.

And, obviously, congrats on finding such a great car with so very little miles! What a dream! ... Pictures of the car would be great, if you could post some!

Edit: Search the board for "oil chart" or something, I'm sure you'll find it already on here somewhere.

The weights are also on the back of the oil container so you can look when you're buying.

^^ That's true. Oil weights may have even changed a bit since the charts were made, so best bet is take a look at the oil at the store and see whats best for your climate. Just go with Mobile 1, and synthetic if you don't mind the cost, otherwise regular isn't bad to use.

Hi Dean320
It must b an as new W140 you have there , i dont know exactly how many Miles 12,411 in Kilometres is but seams to be fairly new or just running in ( a car 10 Years old ,lol ), to me , so why add a different Oil than what Mercedes Originally Delivered the Car With,wouldent it be a wiser decision to get Original MB oil ,specific for W140 Engines,than any other Brand out there,i know it may cost a little extra but you probably have one of a Few if any W140's with that kind of Milage,congrats on the Purchase .
Mobil 1 is the one in any Case but i thing that MB oil could b a little cheaper ( ? ) ,i dont know /
Ciao & look after the Beauty ......:thumbsup:

There's so much confusion about oil it's kind of ridiculous really. Your car was delivered originally with conventional oil. The requirement, in the U.S. only, to use synthetic oil on 98+ FSS cars came later as a product of the FSS lawsuit settlement. That lawsuit effected only U.S cars. In other markets conventional oils are still approved for 98+ cars. In any case the problem that initiated the lawsuit was the 98+ 112 and 113 motors. Your 104 motor is a holdover from the prior era and never had any problem with conventional oil.

The other great myth is that Mercedes, the factory, recommends Mobil 1. The factory actually approves very specific lists of oil by year and market. The MBNA U.S. market recommendation of Mobil 1 is the result of a marketing and diistribution agreement in the U.S. MBNA is paid to say that so it is hardly an independent and objective assessment of your interests. Better to listen to the factory.

^^ Some great information there, in fact that's right, here's a list I stumbled upon online of MB approved oils:

Mercedes-Benz Engine Oil Recommendations

They market Mobile-1 as the best choice but the factory says your options are open to other's.... Mobile-1 I think, is a great brand of oil, not to say there would be anything wrong in particular with the others, your choice. Really, as long as you've got good clean oil in your engine you're in good shape, it's mostly preference.

Thats exactly right the preference for Mobil 1 is a marketing agreement, it's still a bloody good oil though. That being said I'd run any decent synthetic from a major brand without thinking twice.

Good Luck with your Mercedes - Benz . You will find out that this is a GREAT Car. I have a Mercedes- Benz S Class 1996 S320 Long Wheel Base, 99,000 miles. I was advised by two MBZ service advisers at different dealers that I should change to synthetic oil on my car. I have done the change and have found no problems. I use synthetic oil in all three of my MBenzs.The choice is yours, depending on your pocket.
