pathproud Posted August 4, 2008 Share Posted August 4, 2008 Can you start using synthics on a -99 pathy 86k that previously was on regular? Was told that it would be next to impossible to flush out the regular oil in order to start the new regime? Link to comment Share on other sites More sharing options...
FUELER Posted August 4, 2008 Share Posted August 4, 2008 first id go with a synthetic blend, and then next oil change id go to full synthetic. Its a great way to gradually change over. Link to comment Share on other sites More sharing options...
laxman0324 Posted August 4, 2008 Share Posted August 4, 2008 Ive never heard of any problems with changing over, I did mine at 118k. I just used the Lucas Oil additive to help condition the gaskets just in case there is some leakage. Go for it, mine runs like the engine is brand new.

94extreme Posted August 4, 2008 Share Posted August 4, 2008 SHOULDN'T BE AN ISSUE BUT IF YOUR GASKETS AREN'T ALL THAT THEN IT WILL STARRT LEAKING AS THE SYNTH. OIL HAS CLEANING PROPERTIES. Link to comment Share on other sites More sharing options...
arcano Posted August 4, 2008 Share Posted August 4, 2008 I recently switched over my '98 with almost 100K miles from regular oil to synthetic with great results, so I say go for it. As FUELER suggested, I did a couple of oil changes with Castrol 10W-30 Syntec Blend to sort of “flush” the regular oil out, but I really don’t think it’s necessary. Then, about 8 months ago I switched to Castrol 10W-30 Syntec fully synthetic motor oil. I have done about 3 oil changes since the switch (every 5K miles or so). So far I've had no problems with leaks, and the engine consumes absolutely no oil. Just like before with regular oil, I fill it up to the mark, and when I change the oil a few months latter the dipstick reads at the same exact spot. I've always done good maintenance on my engine, so it ran very well before the switch, but I swear that after a few oil changes with synthetic oil it has made it run even smoother, especially right after startup. By the way, I recently also switched to Red Line Synthetic oils in the differentials, transmission (5-speed), and transfer, with the same great results.

CALPATHY Posted August 5, 2008 Share Posted August 5, 2008 I bought my 97' Pathy with app. 121,000 miles on it. Previous owner did all maintence at recommended scheduled intervals with recommended lubricants. I changed to synthetic engine, manual transmission and rear end lubricants with no leaks or burning. The only negative was that it cost a lot more. Link to comment Share on other sites More sharing options...

pathproud Posted August 7, 2008 Author Share Posted August 7, 2008 Thanks! Great advice about first "flush" it out with a synthic blend and do next change all synthetic. Link to comment Share on other sites More sharing options...
