A big thanks to Robert Patton for the heads up on the diminishing supply of higher quality CI-4 lube oil
(page 52, Issue#58, TDR). I stopped by several places and only found CJ-4. My John Deere dealer had plenty of CI-4 "Plus 50", and is unaware of the CJ-4 dilemna. At only $12. 84 per gallon, I bought enough for two changes. The "Plus 50" refers to their proprietary sales point: use this oil with John Deere filters and you can double your oil change interval. It occurs to me that they might have the wherewithall to guarantee a future source of CI-4 quality lube oil. Chevron produces their brand. THANK YOU.
