Regular Oil Pressure on F355

Between 5-6 BAR at 6000rpm with the oil at 100ºC are the correct values according to the manual.

 

Startup: Idle 75-90 PSI
Warm: Idle 35-50 PSI
Track Hot: Idle 20-35 PSI

Warm: 2000 RPM 45-70 PSI
Warm: 3000 RPM 65-75 PSI
Warm: 4000 RPM 70-85 PSI
Warm: 5000+RPM 75-90 PSI

 

Hey, we are still waiting to see some cool pictures of your 355 out and about around Istanbul.

 

Track Hot my OP guage hovers at the first tick ( 15 - 25 psi?? )

is this a normal condition? it goes up as soon as revs come up.

No warning lights. oil is a perfect amber color.

thanks ,

Mine does the same thing, I haven't had any problems. I hope it's normal then again what's normal on a Ferrari? lol

 

i wanted to post this in an article i found about oil pressure that should relive some 355 tensions



"The best way to figure out what viscosity of oil you need is to drive the car in the conditions you will use. Then use the oil viscosity that gives you 10 PSI per 1,000 RPM under those circumstances. For some reason very few people are able to get this simple principal correct. I cannot explain further.

These same rules apply to engines of any age, loose or tight. Just because your engine is old does not mean it needs a thicker oil. It will need a thicker oil only if it is overly worn, whether new or old. Yet the same principals of 10 PSI per 1,000 RPM still apply. In all cases you need to try different grade oils and see what happens. Then choose the correct viscosity.

I used 0W-20 in my Ferrari 575 Maranello. It had over 5,000 miles on the clock. There will be a day (my estimate is 50,000 miles) when one will have to go to a 0W-30. In the future one will have to increase the viscosity to a 0W-40, then a 0W-50, maybe. You should use whatever it takes to get 75 PSI at 6,000 RPM during the lifetime of the engine. This formula works in all situations.

Some people have tried this and occasionally get a somewhat low oil pressure while at idle. This is fine. There is no stress on parts at idle, the smallest oil flow will do the trick. It is at higher RPM where more BHP is produced. This is where we need the flow. Remember that Ferrari uses 75 PSI at 6,000 RPM as the place to test your oil viscosity needs. If your oil gives this value under your driving conditions then your lubrication system has been maximized. Period."

everyone should read and check this know how out at
