Engine Oil Grade
Hello,
i would like your opinion on this:
I use 5W40 engine oil and i have noticed that it dissapears quite fast. In a couple hundred of k's it was almost empty.
In addition when i take the foot of the gas i can see that i have a small "ball" of smoke coming from the exhaust.
Do you think the problem may be in the oil used?
I live in Portugal, so i have to take the highest temperatures in account.
What would you recomend me to use as grade for a Portuguese Cossie?
Do you think the smoke can be a result of a use of engine oil too thin?
Thanks in advance,
Miguel

Does it smoke when hot/cold or both?
The second number, i.e. 40 is the viscosity of the oil when hot, so it isn't that bad just slightly thinner than a 50 weight oil, however the 5 is the cold rating which obviously is a lot thinner than say a 10 or 15 weight.
Remember these are old engines and don't have the tolerances of modern engines and so it's too thin really, Ford recommended 15W/50!

or the turbocharger!i had the same years ago..the bearing of the charger wasn´t good anymore-new bearings and no smoke after that!it was the same like your´s(foot of the gas)
check your bearing clearence!i you´ve to much play in the direction of the axle then the charger will burn the oil.
cheers,

Thank you all.
I will try and change to a 10W50. For road use only can you advise me a brand?
Phs84, thanks for your tip, i will also check the Turbocharger to see if i get rid of the smoke.

I've run mine on anything from 5w50 to 15w50 (always Fully Synth) & most of the time you won't know the difference, except in cold weather when the 15w50 does take a bit longer to pump round the engine from cold.
I always think its best to find the one that works best for your engine & circumstances.

Hi,
i'm finding it quite difficult to find 10w 50 Fuchs Titan Race Pro S here in Portugal.
For now i only found Total Quartz Racing 10w50 and Selenia Abarth 10W50.
Any experience on using these ones?
Regards,
Miguel

Any good quality fully synthetic 10w50 will be fine. The 5w oil is definitely too thin for an old engine and a Cossie will drink this like a fish.
However, if you do track days, then it is worth tracking down the Titan oil (formerly Silkolene, so may still trade as that in your country?), as it's shear properties are way better than most others on the market.
