[C320-list] Engine Oil

[wflowe3 at aim.com]

 My VW is a diesel and the factory recommended oil change is 10,000 miles. It uses strictly synthetic oil, mobile 1  0-40 or something similar.

 FYI - Mobil 1 now comes in an extended performance blend (15,000 mile oil

change interval) and contains additional additives to combat longer term

usage. One may, or may not, believe the corporate claims of Mobil 1 Extended

Performance. Features and benefits according to their website - "Mobil 1

Extended Performance oils are made with a proprietary blend of high

performance synthetic basestocks fortified with an advanced additive system,

designed especially to deliver performance and protection during longer

service intervals. Mobil 1 Extended Performance oils are uniquely designed

to provide outstanding levels of performance, cleaning power and engine

protection, even during longer oil change intervals."



For our engine utilization pattern, 50-60 hours is our normal seasonal usage

and includes enough engine run time each start to allow the engine to come

up to operating temperature to remove crankcase moisture. The estimated

hourly usage to mileage conversion may run something like this: at 60 miles

traveled per hour (considering running at 70% - 80% maximum RPM) for a

15,000 mile interval synthetic extended performance Mobil 1 oil blend equals

an estimated 250 operating hours compared to our seasonal hourly usage of 50

to 60 total hours. That "hours to miles" conversion suggests to me that the

Mobil 1 extended performance blend (15,000 mile oil) has much more capacity

to provide protection and lubrication overtime than we are currently using.

An annual oil filter change each year ensures that potential solid

contaminates are removed from the oil that is cycled to oil pan after

leaving the oil filter. At the higher cost of Mobil 1 and considering the

extended performance blend option, even with extended oil change intervals,

using synthetic oil may remain a far more conservative option than using

dino oil. 



Now if one really wants to enter the fray on the extended synthetic oil

change debate, go to the Amsoil website or Google Amsoil extended service

vs. Mobil 1 Extended Performance. If one thinks that a 15,000 mile interval

changes is controversial, Amsoil synthetic has provided a 25,000 mile

interval for several years backed by its own research. On the Amsoil website

they suggest that oil change intervals may be more about interval oil change

"revenue cycles" than actual oil protection science now that many consumers

have long accepted the corporate line & reasoning for 3,000 mile intervals,

etc. rather than considering the "return on one's investment" in paying more

for synthetic oil, especially when considering the consumer advantages of

extended service intervals.

What Jeff said - East Coast Yanmar rep agreed synthetic was acceptable for

our 2001 Yanmar.  He made the caution that the engine may leak and may use

more oil.  No leaks and no noticable consumption increase.  Note - manual

says not to use synthetic.  Yanmar recommends synthetic for some engines and

not others.  That Turbo may be one of the recommended uses.  We use the

Mobil One "Diesel" synthetic and are happy with it.  But the oil is changed

on a normal schedule for the reasons that Jeff mentioned.  I want the

improved lubrication that I believe synthetic oil provides, but want to

remove any potential moisture or acid contamination on a regular basis.

YMMV
