back to topic. I use 15-40 diesel rated in my 95 e320. Gonna try the synthetic stuff this week..... go 7k in between changes rather than 3500.

I went from full syn to the diesel stuff to save money...

I also got the socket to remove the oil filter housing cover from autozone.. $5

It's all about preference. I need some oil filters. I'm due for a change. Last oil change one of the stupid metal tabs that holds the screw for the belly pan went inside the frame. Yaaar

Use Delo 15w-40 in our 88 W126 with the M103. Actually just changed it today.

I've been using Valvoline Maxlife's 10w-40 in the winter, and their 20w-50 in anything wrong with that? I've heard a lot of people swear by the Rotella 15w-40, thinking about trying it.

background info...94 e320, about 74,000 miles, full maintenance history (all entries show 15w-40), reside in Jacksonville, FL, driven by wife in non enthusiastic driving style, 3500 mile oil change intervals

I use 10w30 in my Miatas, non synthetic, change at 2500 miles mainly because I like wrenching on the Miatas

Mercedes put fully synthetic 5W/40 oil in my M104 engine when I bought it from them and it's had the same ever since. Always 5W/40 but various makes. I've never been that desperate about the oil as long as it's 5W/40 Fully Synthetic.

Engine's fine after 20 years and 370 K KMs.

Synthetic oil from the factory in a 104 motor 20 years ago? That can't be right.

Why not? My 1988 was delivered with M1 15W-50.

No, Lee, I used Mobil1 15W-50 until 1994, then switched to Castrol GTX 20W-50 at the recommendation of my indy in West Palm. Been using that ever since. My new indy here in northern Cal concurs that I should stay with dino. Hard to know if the synthetic oil gave me any sort of advantage during the early years. My gut tells me 'no', but that's a totally unscientific conclusion.

That was about 10 years before synthetic oil from the factory.

15/40 Rotella T Dino- 7 qts exactly. 5K interval changes.

Car has 155K k miles and climbing and has NO NOTABLE USE BETWEEN CHANGES. Heck, oil looks almost as good coming out as the stuff going in.

Can't beat that with a Tank. This is one hell of an automobile.
