Hi All. First time poster here. I am not the most clued up on oil but know a decent amount of background info.
I have a Mazda MX6 2.5 V6 manual. It has 140000km on the clock (roughly 88000 miles). I have been using generic oil (20W50 as suggested by Mazda dealers here) but would like to change to a higher quality synthetic oil.
I have read up a lot on the MX6 forums and what seems to be highly recommended is Amsoil, Royal Purple and Mobil 1. RP is prohibitively expensive here, and M1 is not readily available (sometime they have stock, often not). Amsoil I did not think I could get but found a supplier here at reasonable prices.
My two main questions are:
1. which oil to go for. Other than the Amsoil which I mentioned, I can also get: Shell Helix, Castrol GTX/Magnated and the new Castrol Edge, Caltex Halvoline, Petronas Syntium.
2. which weight should I look for? The Mazda dealers suggest 20W50, the MX6 forums and handbook suggest 5W30.
In South Africa (JHB, quite high above sea level) it is relatively hot. Temps average 25-30 in summer, 15-20 in winter. Minimum temps hardly go below 5 (and that's dead of night only).
What I was thinking was using the Amsoil 10W40. Would that be a good choice? I fear that 5W30/5W40 may be too thin perhaps?
