Like many people for years I've been using Castrol Edge 10w60 oil (at 7,500km intervals with new filter).
The way I use my car the engine never gets hot enough for sustained periods to really justify 10w60 so I asked my (very respected) tuner who suggested Penrite 10 Tenths 10w40.
Problem is like Edge 10w60 it's quite expensive unless on sale. Eg. currently $74.99 at and Autobarn. Repco $79 normally, $72 for RACV members.
Therefore, just like the Castrol Edge thread, this one would like to know of any Penrite 10 Tenths fully synth sales coming up please.![]()
