My last UOA with Havoline 5w-20 was just a tad under 5,000 miles and it held up very well

and now with winter weather here and the loss of my dad's heated garage I'm not looking forward to a late winter change. So, with the addition of LC at 1 ounce per qt. initial dose and another ounce every thousand miles I think I'll take the thin, el' cheapo Havoline dino out to 7500 miles. Of course, I'll have the drain analyzed to see if the LC really did it's job.
Am I crazy? LCD says 10,000 mile changes with inexpensive, conventional oils are recommended. BTW..the filter is the OE Mazda cartridge filter which is a PITA to change.
Personally, I'd rather just stick with 5,000 mile intervals and no additives but if LC does what Terry, Mola and others say it does AND keeps my fat arse off the cold asphalt this winter I'll be happy.
