Using Castrol Edge Sport 0W-40 in a 30 year old engine?

having had 4 so far, i think it depend on the temperature where you drive, and how many limes you go until you change your oil. its hot and humid here in Georgia, so i change my oil in my fun cars every 6 months. to me its cheap insurance, and i barely put 3000 mile a year on any of them. my carb Ferrari's seemed to like the 10-40 and thinner oils, as 20-50 seemed a bit thick. Dr Haas has some excellent oil threads on here.

your 308 is beautiful, i love the clean lines of the euro cars. i am hoping to get a euro QV GTB.

 

Hi Patrik,

If you drive your car a lot in very cold weather, it may be fine, but personally I think it is too thin for the old engines. I run the 10-60 in my '82, oil pressure and temp beuatiful, but, of course, no frost here in Cape Town.

Bear in mind that the modern engines this oil is intended for are built to much finer tolerances than the 308 engine

If the pressure is fine, keep a watchful eye on the oil temp and make sure that it doesn't stay too cold.

 

hello,
I use mobil1 0W 40 in my beloved.
UK weather is neither too hot, nor too cold, and the oil performs very well.
Recently in Europe the oil coped well but tends to dilute somewhat due to the carburettors ... also at around 9,000 feet carbration wasn't too great due to the lack of air > runs rich > dilutes oil.
Back home and 4k miles later, oil pressure is not too brilliant, so she's now due for a change.

Oil temperature has always been consistent.

0W 40 needs to be changed at 3,000 mile intervals, in my opinion.

The original requirement is 10-50W AGIP, IIRC.....

And as noted it'll sheer down quickly as well as fuel dilute in an older engine...

IMO, only a 5-50W or 0-50W is an improvement.

Here in the tropics of Texas, we'll see 100 degree ambient during the next month, I use a Royal Purple 20-50W in the summer, I think the OP will infact see pressure problems as his oil ages, or else he has a damned tight motor! LOL!

I'd never go below a 50W myself, and the first number is actually a "cold flowability" ratng if I read Dr. Haas' data correctly, the lower the better, unless heat/cold is an issue..

 

Hello from Germany,

since you are in Europe ( ? ), it should be easy to obtain Agip Sint 2000. Though it's 10W-40 nowadays and was 10W-50 back in the days, when our cars were new, I use it since 12 years without any slightest oil problems. Oil pressure is fine, no significant delay in oil pressure on startup - provided that there's no filter problem -, and the engine internals are absolutely clean.
We simply don't need the 50 viscosity. Neither on speedlimit free german Autobahn conditions at 35 centigrade, nor under any other circumstances.
And since I always purchase a 60 ltr. barrel, it's even cheap for me. Nevertheless I change it annually, no matter what mileage.
The only thing to think about is, when a car ran with mineral oil for a long period. When one switches to synthetics or semi-synthetics like the Sint 2000 it's possible, that old sludge will come off, collect in the oil pan and plug the sieves. This is especially important with the Agip Sint, because this oil has a significant cleaning effect.
I tried this on an old Volkswagen, which has run ~ 200.000 kms on cheap dino oil and was amazed about the amount of sludge I found in the oil pan after ~ 10.000 kms with Agip Sint. But after removal of the valve cover I found a clinical clean situation.

Best Regards

Martin

 

Beautiful car Partrik, looks better with the windshield in place too!

I would use the Castrol Edge 0w-40, it is a very good product, though not readily availabe here in the States. If pressures look fine, and oil consumption is in check, drive on.

I use a similar product Castrol 0w-30 that is imported from Germany to the States that is a terrific oil. I use it exclusively in my BMW. I am thinking of using it in my F355 as well, as it tests out at almost a 40 weight at operating temperature.

 

I along with many others are using castrol 20 50. Contrary to the wisdom here I have been told that the older cars need the increased film strength . 15 years and car runs great + no oil usage whatsoever.....

I used 20W-50 in my Dino, as recommended by the master mechanic at Algar. He liked it in all the older cars. Changed it once a year before the Spring - Summer Driving season. Car was stored in the Winter.

Castrol. although with the additive changes here in the US, Castrol High mileage might be a better choice going forward. I know we've talked oil to death here, but I still find the topic interesting.

Now, lemme go grab the manual for the 360 and see what kind of oil I should put in there.
