OIL PRICE WAS VERY GOOD BUT U DIDN'T ASK ME ABOUT MY RECENT IGNITION COIL PURCHASE. BUT I WILL TELL YOU I PURCHASED THE COIL ON LINE AND WENT TO PICK IT UP AT THE BRICK NJ STORE I WALKED OUT GOT TO MY CAR OPENED THE BOX AND IT WAS DAMAGED SO I WENT BACK IN AND ASKED FOR ANOTHER ONE AND THEY SAID IT WAS THE ONLY ONE IN THE STORE I HAVE TO GO TO LAKEWOOD NJ STORE AND THEY WOULD FILL OUT A EXCHANGE FORM THAT THEY COULDN'T TAKE IT BACK SO I WENT TO LAKEWOOD STORE TOLD THEM THE PROBLEM AND THEY LOOKED AT ME LIKE I HAD 3 HEADS. THEY NEVER HEARD OF THE EXCHANGE FORM HEY ONLY HAD ONE IN THE STORE TO SELL ME AT FULL COST.NO ONLINE DISCOUNT MY CAR WAS APART IN THE STREET SO I BOUGHT IT. I WAS NOT HAPPY SO WHEN I GOT BACK TO MY CAR I USED TAPE TO HOLD THE PLUG ON TO THE DAMAGED NEW COIL AND RETURNED THE ONE TO LAKEWOOD THAT I PURCHASED . AGAIN I WAS NOT VERY HAPPY WITH ADVANCED AUTO PARTS.

DON'T TRUST ADVANCE WEB SITE!!
DON'T TRUST ADVANCE WEB SITE!! I bought this per recommendation. It is WAY too heavy. It was the first change I did. The oil is probably fine, but double check the specs. thank goodness I had to stop and get another qt. and discovered the error.

Good for Jeep 4.0L engines
Used this in my all Jeeps for many years straight 6 blocks flat tappet tractor engines . This has zinc in it which is good for older inline 6 cylinders mostly all my Jeeps I've owned over the years made it over 200,000 miles my current Jeep is 2004 grand Cherokee 4.0L engine it only used shell rotella T4 10w-30 it now has 216,000 miles still going strong! However the zinc is little hard on catalytic converter I've changed 2 on this Jeep over all years I had it bough it brand new off lot back in 2004. Couple off roaders swore by it years ago I switched over to it years ago and never looked back
Bottom Line Yes, I would recommend to a friend
A Must For My Flat Tappet Cam
Great oil! This oil still contains 1,200 PPM of zinc (ZDDP) & is just what you need during break-in & to help maintain flat tappet cam/lifters.
Bottom Line Yes, I would recommend to a friend
Best for 7.3 powerstroke
This is all I use in my old powerstroke
Bottom Line Yes, I would recommend to a friend
I would buy this product again
I will buy more when you can buy more than 2 gallons at a time. I need 3 gallons for my diesel. Please don't put a limit on gallons you can order online!
Bottom Line Yes, I would recommend to a friend
