hi
i know there is a lot said about oil types im just curious as to what people find the best to run in a 899 seicento gearbox. now as i understand it the seicento 899 box is the same box as a cinquecento. the cinq started off with a ep 80 spec oil.when it got fitted to the seicento it crept from a 75/90 gl4 to finally a gl5 spec. does anyone know if the internals were altered or was this a case of fiat just specing the latest oil. also they spec a fully synthetic oil which is a great leap from good old ep 80.
knowing that gl5 spec is not good in a box that was only speced for gl4 and oils that advertized as gl4/gl5 are just as bad for a gl4 box it all seems a bit confused. auto data say its a gl4 spec??? fiat say gl5 fully synthetic.
