a week or so ago there was a thread on petroleum based engine oils and synthectic. actually i think it started on oil additives.

i thought i had taken away the more popular belief was to use synthectic. i just had a mb source tell me they did not push the synthectic oil. they felt it could damage a seal and cause a leak.

they are right changing a compound touching a resilient seal can cause problems of either shrinking or swelling or loss of resiliency memory. i see it this quite often in the valve business.

let's talk about what everyone thinks on this topic.

i have 143k miles on my 420 and since i'm working on the valve train i'd like to know what everyone thinks before switching.

OH nooooooo, not an other oil tread.
Here's a recap of what's been said on the previous 96 treads on this subject:

I personally spoke to a Mobil Tech and was told." if you car is a high milage car or diesel they do NOT advise you to switch to syn.
and they also don't reccomend extended oil changes with syn.
every 3000 with a filter is fine.
If you lave a late model car that was started with Syn. thats different.

Here's something you may find interesting. I took my '86 560 SEL into a Jiffy Lube ( I know, I know, stupid move) for an oil change. They informed me that they will only put syn oil in MBs in order to keep the factory warrant valid. I informed them that the warranty on my car was long gone....but they said "Corporate told us to only put syn. oil in ALL MBs that we service." And they wanted to charge me $57 to do it. I said no way, bought my own filter and took it to another quick change place. Bad move...they overfilled the engine and when I got home I noticed oil coming out from around one of the valve covers. Fortunately they only overfilled by a small amount and the oil burned off quickly. But I learned a good lesson....no more "quickie lubes" for my car. It is now going to get all the oil changes at my regular independant MB shop. May cost a bit more but I know they know how to to the job properly the first time.

I use whale oil. As I live on the coast, it's an easy thing for me to dash out in a boat, wrangle a nice large whale, tie it to the top of my 250, and take it to my local whale pressing business.

Works great, and I never need to worry about lamp oil.

WD-40 works well but since I live very close to the ocean I prefer to use beach sand.

It is very inexpensive and to date I've not had any oil leaks at all. I'm also thinking about using it for my next transmission service. I'll let you know how that works out.

I recommend milk. Hey, I'm from Wisconsin, we have alot of it around. I recommend raw milk, lots of milkfat for extra lubrication.
Excellent flow rates at low temps. Don't use skim, really poor lubrication properties.

OK now that it comes to secrets, here goes!

In a big blender, 6 ripe bananna peels, one cup of honey, 2 qts Jack Daniels, 4 ripe figs, one lb Hersyeys light chocolate, and 2 tins of 3 & 1 Oil.

Blend for 1 to 2 min, strain, and mix with your old Harley oil you just drained after 1500 miles, (hot) and shake it up.

Add to crankcase as usual, don't forget to open and eat the old filter elements, as they are high in vitimins and tasty!

I consider it a crime to waste good whiskey in any engine.

I refill with 6.3 qts. of tap water. Never use distilled water as it will rust the cyl. walls.

Jackd,

Thank you for compressing the ninety something previous oil threads. What compression algorithm did you use to come up with those strings?

Have a great day,

I have always preferred antisieze.

Who remembers the Griswolds in National Lampoon's Christmas Vacation? Remember the super friction reducer that was put on the dish sled? I'd like to get a hold of that stuff!!
