Hi all
Another think I need to ask for the same model. Ferrari 308 GTB dry sump. The proper engine oil according to the manufacturer is the Agip Sint 2000 10W 50. However this oil doesn't exist any more. Some put synthetic oils with different viscosity but this affects the oil pressure and the engine tolerances as well as the temperature.When I bought my car was running in fully synthetic (very expensive) 0W 30 (almost water). therefore the oil pressure was never right. So..What is the equivalent of the AGIP SINT 2000 10W 50? thanks again.

Hi,
A bit late to post but I have the same car.
I have used both Motul and Shell, with the Motul 300V Competition 15W50 you have an oil pressure of 4,5 to 5,5 with less range.
After a service at Ferrari, they change to Shell Helix Ultra 5W40 (advocated by Ferrari), and my pressure was from 1 (1000r/m) to 4,5/5 (high rev) which I consider as too low. I will definitely get back to the Motul next time.
I precise that my oil hoses are new.
You can also adjust the pressure around the pump but I don't do mecanich myself.
Hope it helps.

308 GTB 1979

Hi Jephma

thanks for the reply. I finaly put the Agip SINT 2000 10W/40(bit thinner) and the engine runs really good. The oil pressure goes to the middle when the rounds reach 5000 as it should. It gets a bit low only when the oil temperature goes up in the traffic. I think this is the closest to the reccomended.

I don't think spark plugs were addressed in this! If the car is stock and you drive it hard (which you should!), used BP7ES and make sure total ignition timing is about 38.5 degrees at 6k+ rpm. If you baby it, use BP6ES. I found the 7s to not have any trace detonation in the high rpm ranges like 6s consistently suffered from. I set these up and tested on a dyno quite a bit.

Carb 308s have weak spark. So a hot spark plug would be better . I use BP5ES. wrong??

That's true, the carb 308 does have a very weak points ignition system, but I would still not recommend going BP5ES. I have no doubt those would have some trace detonation at high rpm regardless of the ignition system in use. BP6ES at the minimum, and if you upgrade to a superior ignition go with 7s.
