This is because of what Dave pointed out, above, about the "W" rating for oils. In my Benzes, I continue to use 0W-40 (Mobil FS European Formula). Works great. In Las Vegas or Phoenix, AZ summers, I think 5W-40 or even 10W-40 would also work, due to the ambient temperature.

When it's cold, I *want* lower viscosity, and all it means is that shearing of the oil molecules will take place a little sooner, vs. if the W rating and the "hot" rating are closer. That's all. However, remember that M-B's computer says to change your oil typically every 10,000 miles (the "A Service"). I do it every 5,000 miles. This seems to work well, because the '03 S430's engine has gradually quieted down over the last couple of years. And in all of my M113-equipped cars, I use exclusively the white "fleece" filters, instead of the paper ones (the S600 and the E320 CDI factory filters are paper, so they're different).

So, you're fine.
Thanks T,
Yes I remember you using the 0w -40 in your cars as well. I also realize that if anything the 0w - 40 will give me better protection in the winter months especially with all the low temps we get here in CT but I guess the biggest shock initially was switching over after 7 years of using the same oil Anyhow I will give this one a shot and who knows, I may even stay with it if I get the same results as you and it gets my engine quiet just like yours
Just wanted to thank you guys again for putting my mind at ease

Only mistake you made was buying it from the dealer all these years! Maybe you are not a Costco member but that is where I buy my "Mobil-1 0-40 European Formula". Some Warehouses stock it, some don't. I buy it when it is on rebate, last time it was I noticed they did not stock the w0-40 in my store but I looked at the rebate sign and the 0-40 was listed. So online I go, sure enough it is there. 28.69 0r 4.78 per quart to my door. At the time I ordered it Costco was offering free two day shipping. So check your Costco if they don't carry it wait for the free shipping and rebate and stock up.

Thanks Wally, and yes I am a member at Costco Reason that I was not getting the 0w-40 at Costco is simple, I was not using the 0w-40 I was using the 5w-40 based on my Dealership recommendations and unfortunately I couldn't find the 5w-40 Formula M anywhere else but the dealership. if I do decide to stay with the 0w-40 from now on I would definitely get it at Costco. Thanks again.

Walmart currently has the 5-gallon jugs on sale for US $22.88. Yep, that includes 0W-40. Yep, I bought some.

You are correct my bad Costco does not carry the 5-40, 5-30 but no 5-40w. Over looked that key issue.

Taking into account it is qts the Walmart sales price 4.57 is a little better then Costco's sale price 4.78. But either is better then the dealer.

Hey Sonny, you're not the only one who buys oil and filter at the dealer. I do, too, however the parts counter gives me a discount since we've known each other for many years. It ends up being a good deal. Moral: get to know your dealer parts team and good things happen
