ECGS suggests Lucas brand non-synthetic for use in axles where their parts are installed. I tend to agree also.

I had 80/90 in the rear of my xj with a lockright. was loud and was grabbing during cornering or sharp turns. Swapped to 85-140 and its much quieter and no more grabbing..

I thought there wasn't much difference, Until I watched the youtube synthetic motor oil test. In a Cold test, You'd have to Heat the Supertech, to get it out of the bottle! As thick as Roof patch tar!

I asked ecgs why they didn't like synthetic. They said the oil ran cooler but the gears didn't. Anyone else have any input on this. I thought synthetic was the $hit.

There's a long ass write some where that backs up what ecgs said. I can't remember the science behind why they run cooler but I know it all came about when Ultra 4 cars started having gear failures when running synthetics. Once they switched back to dino gear oil the failures stopped.
On a side note synthetics are nice but mainly only for the high(er) quality base oil and longer dump intervals.
