yikes! some of you guys are using a very thick 15w40 diesel oil in a gasser?

Sorry im not willing to do that. My S420 has mobil 1 5w30 and has been averaging 25mpg on the highway with 91 octane.

My diesel has Amsoil 15w40 full synthetic.

yea i know, i find it equally as scary. But its recomended by Mercedes to use dino 15W40, so i continue to use it and that's all the car has recieved since it was brand new. BMW meanwhile i've heard suggests 10W40 for pre-99 car's but consider 15W40 just as good to use. I really blame mercedes for not putting enough effort to recommend/promote certain oils according to regions and the climate effects for the choice you make.

I don't get it,
I had better writing,and punctuation skills,as a kid,than I do now.
Now,I'm frequently accused of over punctuating,and spelling errors.
The spelling errors are not how I write though,and I almost always spell correctly.I'm still new to computers,and keyboards alike.I very often will hit a button for a letter,but it won't register for some reason.Since,I type slow,you need to read my posts slow(lol)I still need to look at the keyboard also.The "N" key on my keyboard took a walk a long time ago,when something fell on it,and broke the white plastic retainer for it.I've yet to get a new one.I just bought the lap-top over Thanksgiving,and it's still under warranty.I just need to go to Comp-USA with it,and get it fixed,but really bussy lately,and haven't had time.
You fellas read my stuff all the time.What do you think of my spelling,and punctuation?Honestly..
I try to use good grammar,and proper english,the way I talk normally.I think I'm pretty fair in that department.

That whole thing would read a lot easier if you could remember the following:
1 push of the space bar, after a comma
2 pushes of the space bar, after a period.

For example:
I try to use good grammar, and proper english, the way I talk normally. I think I'm pretty fair in that department.



In keeping inline with the topic... My vote is for 15/40 also, unless you think your climate can handle 20/50.

Ok , Thanks Larry , I hadn't realized my words were so bunched up , until you pointed it out . 15/40 Rotella-T , is my number one choice also .

One seemingly minor detail....

Put the comma right after the last letter, not evenly spaced inbetween

Like I did in the sentence above, not like this: "....last letter , not evenly..."

A vast improvement will now be even better!

Ok, thanks Larry, I guess I need to brush up on my lit. skills a little bit.You do understand I'm pretty new to typing, too. It's taking me like three minutes to write this, and the longer I make it, the longer the time it takes. I'm not particularly crazy with the flatness of this keyboard either.My home p.c. has that banana shaped one with the bulge in the middle, and a lot easier to type on. I think too much on this will give me carperhal tunnel, or however it's spelled. Thanks again Larry.

best oil for any car is to use mineral base oil and periodic changes of oil and filter is the best. Nothing beats that (even sythetic oil can't give you absolute protection, its all marketing hype).

i use 10W-40 dino oil, rated SJ or SM minimum, and change every 3000 miles on my 97 E420

Isn't that a bit thick for a Canadian winter?

He is from Vancouver, British Columbia.
They have NO idea what winter is.

I don't know where u live, or if ur canadian also...but here in the greater Vancouver area, we have very mild winters which include no snow or freezing...so with none of that messy winter stuff...15W40 is no problem to use at all...


and i think manny put it best:
He is from Vancouver, British Columbia.

Any MB dealer who gives this advice is a bleeding idiot considering the class action suit MB lost over sludging in the M112 V-6 due to the use of dino oil changed at FSS intervals. And those are pre-2000 engines.

Castrol?
