I have been using 5w50 for a long while.
Heard dat thiner oil oil is good for economy.
is 5w20 advisable for daily driving?
If i go tracking, i'll def use 5w50.

Any comments?
Cheers!

lots of topics covering this wild faye.

Recommended oil for the fto is 5w-30. Lots of people have different preferences. 5w-50 will be thicker at engine running temperature.

I dont know that is has anything to do with economy? ... do a bit of search of the forums, you will find a bit more info.

Never heard of 5w-20. but that may be a little too thin...

I would stick to 5-W50

Or go to 0-W40

Just watch for oil leaks around the cam seals when using a thinner oil, this is a common problem with ftos

Hmm...i am still considering giving it a try...i'll post results on economy once i do it...if i do it...

but e oil seals thingy is a little scary...i'll keep a lookout for it...

cheers!

depends who you ask....

mechanics have told me that the thicker oils can cause the cam seals to leak as it causes greater pressure on the seals due to its thickness....

thats incorrect! I've never heard of thicker oil causing more pressure on cam seals.

I dont see going to such a low rating nescessary! 0w-20? If i live in the chills or canada etc maybe!

papaya.... I am by no means an oil expert, but why is it that porshce for example are told to ONLY use 0w-40 etc, and that fords are told to only use 5w-30 in their manuals.... certain cars require certain specs..

the climate is actually not the huge issue, its the viscocity of the oil at a) start up and b) running temperature.....

A thicker oil is often used when a car engine has not been run in yet, to protect the engine, (either a new car or reconditioning engine) but once run in a thinner oil will be used. The thinner oil will protect the engine much more on cold start where most damage occurs..

the comment I wrote about a thicker oil placing more pressure on seals is only what was told to me by numerous mechanics. I am not saying they are correct - just repeating what was told to me. If a engine has a certain amount of crank case pressure and is forcing a thicker oil to run through it then wouldnt this then push harder on the seals?
