I finally changed my oil at 110,165 with some royal purple 5w-30 (can't find penzoil ultra any more) thought i would try it out and am quite pleased with it so far, but can i really go safely for 10,000 miles on this oil, have an oil filter garanteeing 10,000 protection if i can go that long before an oil change i won't have change oil til this time next year. which would be awesome.did a swap of my spark plugs,>> the old ones were all denso iridiums, put in ngk ix. took four hours but i cleaned all the coils and put on anti seize on the new sparks, despite the being suggested antisieze wasn't required. the ones on the drivers side took a little longer cause of all the fuel, brake, and vacum lines being sort of in the way along with a neighbor coming over and chating me up. but i also took my time and made sure not to cross the threads and torqued every thing down properly, i thought of indexing them but rather they be snug as opposed to indexed and to loose. now i need an oil change. the belt is sqeaking a bit. other wise she seems to be purring. i have a 4.7 v8 double cab 4wd with 109999 miles on her.
also was pissed to discover when toyota did the coating to my frame they took off my engine cover/skid plate and only put 4 new bolts in stead of 5 old or new bolts, but it went in with 5. so i will have to go ***** at them.
