I have been running Castrol GTX HM last couple changes.
Also been running it in my 93 Taurus SHO.
In the truck I used to run mobil oil, the regular mobil.
With the cast the last oil change I went to 5w30 instead of the 10w30 I useually use. The 5w30 is what mazda recommends but it seems to smoke more on first start after sitting a while (valve guides are gone) The thinner oil I assume?
Ok this post is to do with what brand of oil should I use. I'm sticking with dino since both engines have over 100k. Truck has 166k and car had about 130k. My dad raised me up with him preferring Penzoil in his Fords and have seen good results from about anything but recycled or bulk oil as long as it it changed every 3,000.
I was wandering which is the best tried and proven oil.
I like protection and how well the engine will look when engine work comes due. Sludge, dark brown aluminum to red, and so on.
I haven't really ran any Havoline and don't know if I'm ready to switch yet. I know it's one of the preferred dino's on here from reading and seems Castrol not very little different, just some swear by it.
i'm not going to get into trying one of each and getting samples and haveing them tested, I was wanting other peoples results.
Price really doesn't bother me when it comes to oil.........................
Btw: I'm new here lol..............
