Hey guys/gals,
I'm looking to change things up a bit at the next oil change, not sure where to go though... (2000 5.4, truck in sig.)
At the moment I am using the Castrol GTX high mileage... Is this oil in FACT a synthetic blend motor oil? I have heard all kinds, but do not have a definitive answer yet.
The motor in my truck is at 214,000 KM and does not/has not burned or leaked a drop since I bought it, and is still golden after 2500 KM.
I'm looking at the Valvoline Premium conventional motor oil. Now this oil is not a high mileage oil, and does not have the seal conditioners that the GTX high mileage stuff has. Will using the conventional stuff without the seal conditioners hurt my seals?
Another oil is the Valvoline Max Life semi synthetic high mileage oil. This is a confirmed semi synthetic. Differences between this and the GTX high mileage stuff?
Should I just stay with the GTX high mileage? Go 100% conventional? Full Syn. is defiantly out of the question. Looking for opinions. I like to do my homework before I use any product.
Thanks all!
Derek.
