I will post some data. RP 5W20 saw pretty low wear even though I stressed the engine like hell. Below are numbers for lead (Pb), iron (Fe), copper (Cu) and tin (Sn) in ppm. RP 5W20 Pb 7 Fe 10 Cu 9 Sn 7 CLTR 5W40 Pb 2 Fe 13 Cu 11 Sn 5 Conoco Pb 5 Fe 24 Cu 13 Sn 11 The RP 5W20 saw 5k mileage, CLTR 5W40 saw 7k mileage and Conoco is 9.5k mileage. Longer oil service will lead to more wear so it looks OK but the jump up in Conoco's case is a little too high. Antiwear levels, RP and Conoco are equal. The zinc (Zn) and phosphate (P) are indicative of the ZDDP antiwear additive. Both are high but calcium (Ca) for Conoco's case is the highest. But Conoco is lacking in molybdenum (Mo). RP and CLTR's trump card. RP 5W20 Zn 1500 P 1123 Ca 2213 Mo 87 CLTR 5W40 Zn 993 P 845 Ca 1847 Mo 41 Conoco Zn 1443 P 1135 Ca 3146 Mo 1 Comparing with the data above. Seems like the engine likes something with molybdenum in it together with the Zn. It seems to like SAE40 oil (which engine doesn't?) but I experienced poorer fuel economy. With this, I will go back to RP 5W20 to see what better results I can squeeze out. Those on RP 10W30 are already on something good.

OK attached is the UOA report on Conoco Hydroclear Super All Season Diamond 5W30. For some strange reason, the Si levels have not gone down. I will be checking on the intake system. As long as this is not solved, the bearing wear is going to be there no matter how good the oil is. I'll be check out the grommets and all the possible areas where a leak will occur. As usual, anyone interested in Terry's comments just PM me. 87128_NGEE1_E140-35083-1642.pdf

I'm looking to change the colour of my rims as the normal silver colour is getting boring. Many guys here recommend Yew Lip. I shld be going there to get mine done, as well as the spraying of my calipers. My question is: has anyone spray their rims to a different colour and is very satisifed? Any pictures to show? I'm thinking of metallic bronze and similar colour along that line... No white, as regular maintenance is needed. My ride is black, therefore wrx gold will not look nice. Anyone pls? comments required as well!! -

I saw a website with lots of dyno tests results, comparing the differences before and after installing mods. Installing a cone air intake charger ONLY, will result in big drop in horsepower and torque during low rpm.. By low rpm, I mean 1000 - 3000 rpm. Sports intake vs stock intake http://www.ttzd.com/rides/dynocharts/dynochart16.html Torque dropped as much as 155 to 120. pulley vs lightened pulley http://www.ttzd.com/rides/dynocharts/dynochart33.html Big overall gain throughout power band.. Hp 263-282 Tq 329-353 Finally... NOS and no NOS http://www.ttzd.com/rides/dynocharts/dynochart44.html
