if that's the case, then seafoam did it's job. changing plugs is protocol after sea foaming, and possibly the o2 also. anytime u loosen up that much carbon and nastiness in te chamber expect to be replacing plugs and o2s.

 

I run Valvoline High-mileage 10W-30 with a Purolator Gold Filter and the Jeep seems to love it.

 

Yeah I go puralator gold with 5w-30 (cold winter) high mileage.

 

where's the Jeep?? again just because your vehicles have mileage doesn't mean there isn't internal damage being done... as stated I used to run fram all the time until I dug deep into the heart of the matter, now I'm skeeeerd of them and rightfully so...

I think they're both decent and without going into a great debate/war, bottom line is weight/season, filter media and OCI's...

I have new plugs do you think just a good cleaning would suffice?? I guess I better do this before I put on a Cat so I just have one o2 to replace

On my next oil change I think I'm going to run a quart of MMO like cruiser does religiously, probably 10w30 also...

MMO question::
If running 1 Qt MMO what is the recommended OCI??

 

Only thing I have to say is, Fram is the worst POS you could ever buy for any vehicle. Period. Never. Not once. Just don't even go there. That is all.

 

The guy with the 612,000 mile XJ uses Tufoil as an additive, I rarely see anything on Amazon with a full 5 stars, customer reviews are extremely positive.

One reviewer claims a small sip cured his cancer AND male pattern baldness..........OK, it didn't really do that, but the stuff has good reviews anyway.

 

PTFE in the engine?

 

i run Rotella 15/40 all year round in all my junk...even in my Flathead Ford. (Zinc content is high and great for older engine designs).. I am in So cal so my ambient temps are in the mild zone...I use Seafoam in the tank on all my vehicles and when I change Fuel filters in my Dually..it does a great job cleaning the injectors.Marvel Mystery is good stuff for neglected crankcases purchased from stupid previous owners...sludge be gone

Perfect combo....

 

Lol. PTFE is more commonly known as Teflon. You know why they aren't advertised as Teflon additives? Because DuPont revoked the license to use the trademark after the FTC investigated false advertising claims and they were PROVEN not to work worth a damn.

hey old neighbor !! just moved from Riverside (well 6 yrs ago )...

its a love/hate relationship, sometimes I miss it other times, nahhh

all the vehicles and all the years I've been driving I'm embarrassed to admit I've never even tried MMO..

 

That's a good question since this a Cherokee forum. Its in the works. Decided to sell the 4 Runner, the Isuzu is actually belongs to my son now. I have been using this forum to learn from experienced Cherokee owners before I go out and purchase something. Its been a great help. Enlightening and confusing all at the same time.
I have not been using the Fram filters by choice. I have limited product availability in Hawaii. We have one WMart and one KMart on island. The other choice is NAPA. I have learned here that they are respected filters, the Gold anyway. As a result I started buying the Silver as they are cheaper even that the Frams and better quality? I have always thought the hype about NAPA Gold filters was just that , but maybe not. Who knows.

 

Silver is fine if you change your oil every 3500 miles or so.

 

trust me brother you aint missin much out here except maybe Big Bear and the desert for Wheeling ...only thing good here is the weather and the wheeling...the people byte and gas is still over 3.70 a gallon, diesel is at 4.15 go figure..I am old and when i was a young whippersnapper gas was at about 60 cents a gallon...too much traffic and too high of taxes stoopid politicians that think Hybrids should be alone in the carpool lane, smog laws are a joke and borderline corrupt and nothing but ALL ABOUT ME people around here....i am only here as my parents are here..i was born and raised in Manhattan Beach...i moved out to Murrieta to get away from people and well it seemed they followed lol
