Oil brand / weight / viscosity in F355

Hi All -

My shop used Valvoline (synth) 20w50 during my last fluid service a few weeks ago. After driving it 2,000 miles (not a typo) since the fluid service, I figured I better check to see if she had burned off a quart (or more). After a 30 minute drive, I checked the oil with the engine idling and I was very surprised to see the dipstick covered in coffee colored foam.

I normally use Redline (synth) 10w40 and the shop agreed to change the oil out to see if that cures the foaming.

What causes the oil to foam?
1) Over-filling with engine oil. Possible (nobody's perfect).
2) Condensation from disuse. Not possible in my case.
3) Contaminants in the system. Possible.
4) Wrong engine oil weight/viscosity for the conditions. Possible.
5) Other?

The first 3 I'm fairly certain of...it's #4 that I'm wondering about (hence the post). Could 20w50 be THAT different from 10w40 and cause foaming?

PS Temps and pressures throughout the 2,000 miles were spot on. Car drove normally and did not seem to be down on power. Fingers crossed it wasn't 'foaming' the entire drive but I have no way of knowing for sure.

Rick- We started using Valvoline full synthetic 5W-40 in my 575M because the Shell Helix Ultra was foaming too much. No problems with foaming at all on my car.

Are you sure they used full synthetic oil? Valvoline makes a synthetic mix, too.

fwiw, our F355 ('95) has had Liqui-Moly 5w40 (full syn) over the past few years (prior owner and me) and really seems to enjoy it. No measurable burn, and no foaming (knock on wood).

355 should have oil level checked with motor off. Due to the plumbing in a dry sump system in some cars it can make a big difference so it is important to do it the factory way. Many dry sump systems the return line either sprays the dipstick or creates so much turbulence the oil level reading can be meaningless.

Prob due to type of oil, some foam, some do not. You are better off with a 5-40 unless you see very high oil temps with your type of use.

I also know, that it is not a good idea to check the oil while the engine is running. So maybe now is the time to ask - how long after you turn the engine off will you get an accurate info about the oil level? A minute?

Almost immediately - I pop the engine cover and have my cloth / shoptowel ready, then go turn it off, by the time I come back and unscrew the oil filler cap the oil is back in the sump.

This was just discussed on the other forum and Dave Helms states to check the oil with the engine on, at idle. I was told the exact same thing from a very well respected Ferrari Tech.

Dave did say some oil foams and others do not. I've not checked mine with the engine running yet.

My Valvoline SynPower 5W-40 was just changed last week and there were absolutely no signs of foaming or any other problem. Oil looked so good coming out, my techs kidded about using it in one of their cars.

Still using that Slick-50 anti-foaming additive, eh? Short of the Shell oilo that our local dealer uses, the only stuff that I've seen that foams more is what the wifey uses in the washing machine.

David- Not me. No snake oil in her at all. My techs and I love that Valvoline synthetic. Dealers add snake oil to 612s and 599s because the owners complain about lifter noise. Funny that with the same engine, lifter noise never bothers 575 owners.

I'm just pullin' your leg...Those complaining about lifter noise might want to consider a Lexus.

It took the Americans from the early 50's to the mid 70's to learn how to make a decent hyd. lifter.

The Europeans needed to reinvent the wheel so ignored our lessons. Mercedes took 20 years to make a decent lifter and today I am not sure they have done it yet. Ferrari in typical fashion have decided to ignore even their European brethren and set about reinventing yet another wheel. I am confident they will be nearly there when they decide to trash the entire project for yet something else.

Mercedes had to go through the process of developing good automatic transmissions from the late 50's to the late 70's in much the same fashion. It was painful to watch and must have been terribly expensive.

Mercedes Benz thought they had invented the desmodromique valve in 1953. Their patent attorneys informed the racing department they had raced against French cars so equipped nearly 30 years prior.

Institutional blinders bred from misplaced feelings of superiority are amusing.

David- I do use snake oil in my blinker fluid.

Brian- How was the vacation? Have you tried any of Dave's lifters yet?

A bit of a thread resurrection but there is some great reading on oil, from a guy on Fchat. It's a long read but worth it. The info corresponds to the Motor Oil Bible, another good technical read that will take you a lot longer.

Dave what kind of oil do you use. I thought a lot of people were using mobile 1 but i see terry is using valvoline.

I know i usually check my oil right after shut off only because it is hard to read when idling

Hey Grant,

I check my oil at idle all the time and have no issues. I use Pennzoil.

See my oil change document here: http://www.ferrarilife.com/forums/pr...documents.html

Kinda off topic but we (the f1) owners need to find a replacement for the speedo sensor if we really cant get them anymore.
