regular or conventional motor oil

I have a 2006 silverado 1500 with the 4.8 litre v8 and it has about 57k miles and needs an oil change. I see blains farm and fleet has there oil on sale for 3.49 a qt. regular oil or full synthetic. it is made by citgo they tell me. I have always used conventional or synthetic blend and have had no trouble with either, but everybody seems to be going to synthetic. which would you use if it was your truck? thanks in advance.

Well, I can tell you my wrecker is on it's third engine (5.7L Chevy) and I started synthetic on this one when we installed it (2005). Last motor threw a rod at 280K, this one now at 340K miles, just replaced the heads (leaky head gasket, not oil-related). When I pulled it apart is was clean as a whistle in the valley and under the valve covers. This is with Wal-Mart store-brand SuperTech oil; I have no idea who makes it.

Cant tell you what to use, but I have used Motorcraft synthetic blend on my Ford V6. 10,000 miles between changes, doesn't use a drop... over 275,000 mi so far. Besides oil and filter changes, how often you change the air filter has a lot to do with it.

Newer engines have a lot tighter tol so the improved lubricity of synthetic is needed and it's simply a better oil. Not going to hurt using it in older enginesI

Synthetic is supposed to be the way to go now, especially for newer engines.

Personally, my rule is to find the oil you like & do not change from that brand, wt or type. That's just me & I am no expert. I have always used conventional, so that is what I continue to use.
Another reason I use conventional in my personal vehicle is, it does use a quart or so of oil between changes depending on what I use the truck for during that period. I don't want to waste or add high priced synthetic oil during changes.
I am also still more comfortable changing my oil every 5,000 miles. Synthetic oil is supposed to last longer... about double or tipple that of conventional oil if I understand correctly. Just personal preference but I don't like using any oil for 10,000 - 15,000 miles. Just me being old school I guess.

In the end, synthetic is supposed to be the best oil technology out there. I think you have to evaluate your individual situation.

When my wife had a new car I used fully synthetic in it, my jeep and her older toyota get synthetic blend, my old pick up gets conventional. I too tend to use the same brand of oil although if another brand of similar oil goes on sale ......

Brand is really not important, its the API rating that matters, follow that and get the cheapest.

This is with Wal-Mart store-brand SuperTech oil; I have no idea who makes it.
I remember long ago reading that Super Tech was made by Quaker State. I do not know that to be a fact. Just like years ago Motorcraft oil was supposedly made by Conoco.
