One other consideration about synthetic:
Regular petroleum motor oil is refined from crude oil, which is a mixture of just about everything on the planet. One problem with refined motor oil is that it is impossible to *completely* refine out all impurities - such as parafin, etc. So, besides being molecularly (sp?) more consistent, synthetic is more pure. Petroleum motor oil would be identical to synthetic IF the refining process were perfect. (The refining process may not be perfect, but, in reality, it is damn good.) |

Years ago I had a meeting with a mobil 1 rep on synthetic oil. Actualy synthetic oil is the same as regular oil. The actual molecule of the oil is 100% the same, since it is the same oil. So I asked the rep if this is true, why is synthetic oil better, and which is the best. How could it be the same oil? He said, If you look at a partical of regular oil, it may be oval in shape, or could be eclipse in shape. No matter what the shape is, there all different shapes, and sizes. Its like having a 10pound bag of coins. Some are dimes, some quarters, ect. Synthetic is simply like having a bag of all dimes. Every partical is perfectly round and the same size. Almost like little roller bearings. I was impressed he did say there is little difference in brands of synthetic. Since the process to make synthetic is almost all the same. To notice the difference in two types of sythetic would be very difficult.
This is also why leaks tend to start with synthetic oils. Regular oil having different size particals can actualy block oil leaks, when you switch to a synthetic on an older motor, you may find a few new leaks. |

My experience with synthetics is that they leak more. I don't use them in anything but my track car (Porsche). I have noticed that with regular motor oil, the oil gets dark after one track event. With synthetic oil, it takes two events.
I don't put it in anything by my track car. But there are many opinions about motor oils, and I am sure many would differ from mine. |

john,
you should check the oil each time you fill with gas, cheap insurance.
Carbon is normal |

I also notice some black carbon residue on the tip of my Tubi exhaust. I heard this is normal b/c Ferrari tends to run at a richer fuel/air mix than other cars. I also heard that after 600 miles I should check my oil level b/c the car goes through motor oil faster than the others. Any idea?
Thx for all the previous suggestions and comments from everyone. |

On the topic of motor oils, IMO there is some advantage to synthetics, it's a matter of choice.
I have used the majority of them and find that of all things DELO 400 15-40W works just fine. I first got familiar with it in modified diesels. They need good oil!
Frequent oil and filter change are the key. Flush the impurities out.
One thought, It used to be Taboo to switch to Pennsoil if you motor has extensive miles.
Oils with high detergent additives will cause them to "clean" the motor. Unfortunately, the filter will only handle so much, then the bypass opens and all the junk is sent thru the bearings. |

Doesn't matter which oil you use as long as its synthetic and as long as you keep the intervals short.

Keep one thing in mind too that A Ferrari holds about twice as much oil as a normal passenger car and using a 5000 mile or one year drain interval You will never have a sludge problem no matter what brand you use. I change a bunch of oil, I can't even get a job at Jiffy lube because I am over qualified. |

I agree with Hans, When I worked in a machine shop, the gumed up motors were the ones that people didnt change often. The brand of oil they used didnt seem to have as much impact. |

John,
I use Agip Sint 2000 10W40 in my 308 GTB also. This was recommended by an authorized Ferrari service center nearby. I, too, am pleased with the results.

John;
I use the Agip Sint 2000 10W40 and I am very happy with it. The car realy ran much better once we started using it, and no leaks that you would typicaly see on pure synthetic's in an older car. The price is not bad, so I will continue with it. |

I happen to have a preference for Mobil 1, but realistically, motor oil has been R&D'ed to death.
I work in a shop that does a lot of motor replacements/rebuilds. Almost without exception, the dead motors have thick gooey crud in them from not changing the oil. Change interval is probably much more important than oil choice.
At 1500 miles, I start looking at the dept store sale ads for Mobil 1. By 2000 miles, I've usually scored on a cheap source, and start watching for my favorite hoist to open up. |

Any major name brand oil will protect your car as good as any other. Just use the correct weight oil and drain intervals. |

Could any one tell me if Agip's Sint motor oil is better than Mobil 1?
If not, which motor oil would you recommend for my 355 spider? |
