Well it arrived yesterday on my porch. OK its in a bule and white bottel and here are the specs: on the front is states Exceeds performance requirements for API Service CH-4, CF-2, CF/SJ Mack EO-M+ and automotive manufacturers specifications. On the back is their creed I guess thats what you would call it; "No other brand of petroleum lubricating oil what so ever, regardless of price will be found superior in condition to MONOLEC ENGINE OIL at the end of any given period of use." Now the non sic observations. The oil is RED deeper red than tranny fluid. I put a little of it in a glass and I put a little Amsoil in another glass both 15-40. The LE seem to me to pour alittle easier (not as thick?) than the Amsoil. Then i rotated the glass on its side to cove the sides of the glass they both seemed to "flow at about the same rate. Nest step the "finger test" the LE felt alot slippery than the Amsoil but for a 15-40 the LE did not fell as thick as the Amsoil. Well any way as soon as my Baldwin filters get here I'll be changeing the Geo Prism (with a toyota engine) 1st, my ram might get a premature change since there is only about 2,000 mi on the Amsoil thats in it.
