Hi All,

Has anyone used Castrol Magnatec Professional A5 5W-30 synthetic oil? It's so darn hard to find a 'true' Class IV 5w-30 in the U.S..

Can anyone suggest one?

Your thoughts are most appreciated

 

I don't know anything about oil classes, but in doing some research yesterday I read some really good things about Texas Tea, a full synthetic brand I had never heard of. Someone on another forum submitted a sample to a lab for testing and it came back with very good results. I found it on Amazon.com where you can buy it in 5-gallon buckets for under six bucks a quart with free shipping.

I'm changing my oil this weekend and would have liked to have tried it, but I just learned about it yesterday and didn't have time to order it and get it in time. I did buy Castrol today instead, though it was that Edge stuff ($25 for 5 quarts at Wal-mart). I think I will try the Texas Tea next time, though, as I will be changing my own oil from now on.

 

Well, we are on a different markets, but here, in Russia, Castrol oils are almost the worst oils. As for me, i prefer Mobil1 0w40 oil, i'm using it in all of my cars, no problems so far. Tests in a lab shows, that this oil is really good choice.

 

As much as I respect your thoughts, I did a bit more research and even Amsoil's 'independent' analysis of the leading so-called 'fully synthetic oils' out there, the Castrol lead over Mobil 1.

So I bought the Castrol Edge Titanium 5w-30 @ 37.00 Cdn for the 4.4L jug

I'll let you know what I think after the install.

Thx again
