Oil / Oil Filter

What do you folks recommend for Petroleum based oil and oil filter ?

Have used AC-Delco and the top-of-the-line XG3890 on my 4.3L/W 99 blazer with good results. I know the lower Frams are junk, but just curious ?

Napa Gold ? Ac-Delco Ultra Guard ?

Far as oil I hve been using the 5W30 Castrol GTX.....truck has 151K on it and runs quite and like a top....and it's stock....

Thanks for your opinions...

Well, I have to say, you have been doing an amazing job and made all the right choice.

AC Delco Oil filter and Castrol GTX 5w30 and you will be good to go.

Just keep on doin what you are doin.

PSSSSST: Maybe change to synthetic.

Just something that was passed onto me by a atv mechanic years ago. I used to run valvoline oil in my wet type clutches on atv's and they started slipping. The mechanic told me to stop using the valvoline oil because it had silcones that causes the slippery condition. He stated to run castrol gtx oil in my wet type clutches because that oil creates more FRICTION. Do you see what I am getting at here. Goes against their ads dont it. Changed the clutches and oil to castrol and never had slippage again, for years now. So you tell me would you really want to run a oil that makes more friction? Who knows, I think just changing the oil and filter ever 3000 is the key to life.
P.S. I dont use fram oil filters, but whats up with being bad? I havent heard this before.

Castrol GTX is one of the finest conventional motor oils on the planet.

What could have making your clutches slip with the valvoline is one of the additives in it.

Besides, you really can't compare these two situations. Totally different applications and situations and probably a completely different grade of oil.

I ride ATVs quite a bit and the ones I have had all used wet clutches. There is an additive in Valvoline, and can be found in any other brand of oil as well, that will make the clutches slip in it. To find an oil to use with wet clutches, besides those reccomended by the manufacturer, you can look on the back of the bottle of oil.

There is a circle on the back, the circle has an outer ring and inner circle part to it. The inner circle usually has the grade of oil in it, such as the bottle in front of me has SAE 10W-40 wrote in the inner circle. The outer ring is then seperated into a top piece and bottom peice. This one has API SERVICE SL wrote in the upper ring, and you should be able to find something similar on most oils. It's the bottom part of the outer ring you have to look at, this bottle of valvoline 10w-40 has nothing wrote in it, making it suitable to use in a wet clutch application, most 20w-50 oils will be safe too.

It's when you look on the back of the bottle, and the bottom of the outer ring has ENERGY CONSERVING wrote in it when you have to watch about using it for wet clutch applications. These are on most 5w-30, 10w-30, or 0w-30 oil applications. The energy conserving mark is telling you that there is an extra set of additives in the oil, those additivies can cause a wet clutch to slip. They are great for automotive vehicles though. It's not an oil brand specific thing either, you can find them in all brands of oil.
