    PP 5/20, 07 corolla, 5,067 miles

    Here is the latest UOA from my 2007 manual 5 speed corolla. Pretty good mix of city stop and go driving and 70mph highway trips. This last OCI was the second run of purolator white can oil filter, so it was on the car for 11,000 miles. Replaced this with PP 5w30 and a supertech oil filter...

    PP5/20, 6071 miles, PP5/20

    5 speed corolla, Purolator L14477. Didn't feel like buying oil, so used the PP from the stash. Used the last of the PP to replace this. I changed jobs recently, and the last UOA was about half on the new commute. This is the first OCI completely with my new commute which is very short and stop...

    YB 5/30, 5458 mi 07 corolla

    Latest UOA. 5speed 07 corolla, filter was the purolator L14477. The filter had been on for two oil changes, so roughly 10k miles on the oil filter. I find this UOA interesting because last winter I ran PP 5w20, and this winter I ran regular conventional YB 5w30. I only had one of the cheapy...

    YB 5w30, 5001 miles, 07 corolla

    Latest UOA. 5speed 07 corolla, filter was the purolator L14477 (larger white can, not pureOne blue). I left the filter on since it only had 5k miles on it. Last filter was on for 10K and did fine. This was the second run in a row of YB 5w30. Filled the crankcase with the same. Now that I have...

    07 corolla, YB Penn. 5w30, 4814 miles

    I think this UOA is interesting because it is a run of conventional after two runs of synthetic. Also, at 20K miles the engine should be completely wore-in. Most of the driving was stop & go traffic around Kansas City. This OCI was also the second on the same toyota oem oil filter (10k total)...

    PP 5w20, 07 corolla 5531 miles

    Here is the UOA from the 4th oil change. I forgot to send in the sample for a few weeks. Looks fairly normal, I wish iron had came down like the copper. This oil interval was over the coldest part of winter with mostly shorter trips that were stop and go. Probably less than 40% highway driving...

    PP 5w20 4,910 miles 1zzfe

    This is from the third oil change in the corolla. It is a 2007 and is toyota allows the use of 5w20. I got the PP almost as cheap as the GTX and am doing the UOA because I couldn't find any for PP 5w20 and this engine. I also do a lot of short trips. My work commute for this interval was very...

    Hi all, 2007 Corrolla, 5000miles total, 3920 on this fill in about 2months with mixed driving. The dealer gave me a free oil change at 1000 miles and put 5w30 bulk oil and toyota filter on it. I averaged 37 mpg with some short trips and lots of stop and go traffic and idling with all the...
