I think that both are pretty good oils. All things being equal (price), which would you pick and why??

Castrol. Based on the VOAs posted of GF3 oils, Valvoline has consitently shown that they blend their oils with the minimal add pack necessary to meet API specs. And Valvoline UOAs that I've seen haven't been all that impressive. Castrol, on the other hand, consistenly shows good UOAs.

GF4 has leveled the playing field somewhat, but Valvoline would still be my last choice among name brand motor oils.

I have used Valvoline all my life and I have been very satisfied with the performance of my engines.

However all things are never equal, especially price.

I wouldn't let anybody tell me what to use so why are you?

I have gotten a lot of free oil from Valvoline. I will continue to use free oil from Valvoline.

Both are very good oils,I prefer Valvoline. Don't listen to the guys that say "Valvoline has a weak add pack", they have no idea what is in the add pack. If you look at VOA's of Valvoline and Castrol you will find that they are very similar. The Valvoline UOA's that you will find on this site are as good as any others and better than some.

We use valvoline in our fleet vehicles (several 6.8L Ford V10's, GM 350 V8's, etc)..

All get the oil changed around 3-10k intervals using 10w30 or 10w40 Valvoline all-climate depending on season... All have been thoroughly abused, and none of them have had any oil related problems.. We've even got a 90 GMC 2500 5.7L delivery truck (this truck sees HEAVY loads on a regular basis) with over 170k having used valvoline it's whole life that is still running strong.

I'd personally choose whichever is cheapest.

Yeah, that's a legitimate reason to pick it over Castrol. [Roll Eyes]

There is absolutely nothing wrong with valvoline all climate. It's just the "in" thing to rip on all climate.

Because I think that's a stupid reason to pick a motor oil. I've been reading UOAs on here since 2002 and IMO Castrol outperforms Valvoline based on those UOAs. How well an oil performs is my criteria for whether or not to use it, not where it's made.

I'm with you! My engine won't blow up with free valvoline.

My VW Jetta seemed to love Valvoline AC 20w50. When i sold it @ 225,000 miles it was running great and never burned a drop of oil in its life.

The guy up in NJ that owns that Volvo with something like 2 million miles on it swears by Volvo recomended Catrol.

I bet your car will be just fine whichever you choose;) I also bet your car would be just fine on Exxon Superflo at a fraction of the cost of the others.

The difference between the two oils mentioned is at best minimal. If the engine blows up it prob has something to do with the engine manufacturer and not the oil.
