Well i wish i read your post before i put the fram on. Ive been using AC delcos and now with the fram she picked up ALOT of valvetrain noise at idle <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> guess ill be climbing under to change it out - i cant deal with that
thanks
also dont know if you guys have picked up on this yet but a AC Delco PF59 will fit no prob on an F-body and give you a little more oil capacity

its all a racket. of coarse they say 3000 miles or 3 months. thats to keep us buying the oil and filters! they had to through in a time line for the people that dont rack up miles.if everyone in the US went from the 3000 mile rule to the 10000 mile interval thats a 35% decrease in sales and loss of hours for the quicky change **** holes. is it a good practice to keep your oil clean....sure. is every 3000 necessary? no. its more to do with your driving habits. i personally do it about every 2500-3000. im brainwashed too. but as far as time line they give....that i ignore. <img border="0" alt="[USA]" title="" src="graemlins/patriot.gif" />

5,000 miles works for me with Mobile 1. If you really drive the car hard 3,000 miles.

My 91 RS has over 247,000 miles on it. Average oil chage was at 4,000 to 5,000 miles on dyno oil. Used Mobile 1 since 165,000 miles. I usually let the Mobile 1 go to 5,000 to 6,000 miles.

dont know if you guys picked up on this yet but an AC Delco filter #PF59 fits an f-body fine and increases your oil capacity a little bit

LAST OF Z28 I agree its all a marketing ploy by oil companies.They have brainwashed us into thinking its required and its not.My SS gets changed ever 10 passes my other rides when I feel like it(every 5-6000 miles)they last to 200,000+ miles still running today.Imagine meeting between oil execs <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> they believe our 3000 mile B.S. <img border="0" title="" alt="[Frown]" src="gr_sad.gif" /> they found out the truth,there goes 25 billion a year in profits.

I change my cars oil enery 500-1000 miles. Car sits more than its driven. Oil breaks down when it sits too long. And any way i am way over protective of my stuff. Sometimes i wish i wasn't like that because people tell me that i waste money when i change my oil too frequently like that

The 3k oil change is without a doubt overkill with synthetic oil. Like I posted above, you can see many synthetic used oil analysis results on that page.

I just changed my sister's oil today, she went 8k on Mobil 1. I sent her oil out for analysis, and I know without a doubt it will come back saying it was suitable for continued use. I'm going to push her intervals even further from now on, since she puts on 500 to 600 miles a week. Changing her oil every 3k would just be silly.
