Some info about SuperTech Motor Oil

[SoftPoint]

Now I know that the SuperTech oil filters are of good quality, and I use them faithfully, but I do have a negative experience to share with this board regarding SuperTech 5w30. I tried this oil in my 99 Ford Ranger 3.0L V6(which I have since traded) about a year ago. When I was goig up a hill, the lifters satrted tapping loudly, and when I was back on a flat road it quieted down. The speed was about 40mph. I had never had this problem with the Havoline I was running. So to me it seems like the ST oil does not flow right under a load and causes the lifters to loose lubrication and "float". Any other diagnosis's out there?
Cheers!

Me thinks ya were kinda low on oil.

Or the bypass valve in the pump got stuck open.

are you sure the engine wasn't pinging?

No pinging, definetly the lifters, they would still tapp for a while one I got on the flat road, then quiet down as the oil got to them.

I've never used the 5w30,but the ST 10w30 and 15w40 worked very well in my vehicles,no problems at all.

I've used 5W-30 S-T oil for several years in two vehicles and other 5W-30 oils like Mobil before that. I don't think it makes any difference what brand of dino you use as long as you don't leave it in the crankcase too long, which is more than 4 mos. IMO!
