I have a 95 XJ W/the HO 4.0L W/130,000 miles on the motor!
1) She burns NO OIL & never has in the many years ive had her!
2) She leaks NO OIL & never has except 4 that rock hittin the pan lip!
3) Compression test was straight across the board,(i think 160psi?).
-- SO,, the argument comes up that i can start running a half synthetic blend of 5w30 for the winter & see how she runs. Ofcourse some say a motor with over 100,000 shouldnt switch; BUT with my motor well kept, sneaking in a half blend could be the key to keeping her in this good condition & maybe push her over the 200,000 mark W/no motor OR head issues.
-- I believe she has "pro long" motor treatment in the motor, tranny, & fuel sys. I put royal purples coolant addative; W/Hi-flo pump & a 3 row rad!! I can keep goin with an MSD ignition,, yellow top,, 140amp alt,, 93octane for the winter,, etc,, etc,,,,WELL,,,, without any arguing,,,, im askin for honest opinions by those with experience with synthetics & those who just know alot about the XJ??!!
Thank You in advance to those that are very helpfull!!
