I normally use synthetic (AGIP Sint) oil in my
86 300 SDL. Since the oil light came on and I have a 3 hour drive to do, can I add a quart of 15W-40 diesel oil until I can have the oil changed? Thanks,-- Jeff

Yes, no problem.

Absolutely. What do you think "semi-syntheitc" oils are?
You guys are nuts -
Most synthetic oils have few if any detergents in them. If he has been using non-detergent oils and now switches to conventional oil, that should be fun
I think, no, I know that you do not know what you are talking about. If an oil meets API or better standards then it has a specified minimum detergency. In a diesel engine of that age then anything with API CE or better will be more than adequate whether it is mineral or synthetic. Any petrol engine built before '98 will be great with API SL and both diesel and petrol engines built since then need high detergent synthetic oil that meets mb229.1 standards.

I called Mobil (1-800-ASK-MOBIL) and a seemingly well-informed fellow named Leo there said that:
I am a believer in synthetics for the following reasons from my own personal experience:
I can confirm that my motorhome burned (and leaked) synthetics about three to four times faster than conventional oil. I evetually switched to Wal-Mart brand synthetic to save money.
I'm a believer in synthetics. I don't care if I burn a quart a tank. I'm still filling my new (to me) 300 SD with synthetic. Heck even at $2.50 every 500 miles the extra cost is only a $500 per 100,000 miles, or about $150 a year the way I drive.

I believe the recommended change interval is 25,000 with a new filter and a top off every 5000.
I largely agree with Paul, vis-a-vis synthetics. They are superior in many ways. He didn't mention there very significant advantages in cold climates.
No. 3 sums it up nicely. Much slower degradation (which gives rise to what was said).
