I posted about this product back in August when I needed a top off of oil from SpeeDee.
I had a problem that my Check Oil Light was coming on at about every 30% of Oil Life lost. SpeeDee the first time it came on it was 1230am after work so I drove to the nearest gas station and bought 3 qts of oil. Put in 2 qts and the light turned off, a few weeks later when I got into my car to head to SpeeDee for an oil change the light came on immediately. I drove down and they changed the oil and said I have a small leak and it was going to cost about $2k for them to repair so I said forget it. Well after that when my car hit the 69% mark the Oil Level came on again and I was only 3 blocks away from SpeeDee so I went for a top off. I told them about the leak and the manager recommended the Heartland product because a lot of their VW customers had success with it. He said it was $25 and to use it every 6months so I said WTH and went for it. He said it is very thick and its supposed to stick to the crankcase and fill up any leaks and what not and also should stop engine tick.
Now almost a month later and down to 38% Oil Life & my oil is in the middle of the dipstick. I noticed recently that it seems my tick has disappeared too. I'm due for an oil changed in about 150 miles so I'll will know by then if it has truly worked.

Re: Heartland High Mileage Oil Changer Review
Well, we know these engines burn a little oil - many leak some also. By thickening your oil, you may be causing more trouble than you are solving. That thicker oil is more viscous than the engine is designed for, and takes longer to pump into all the oil galleries when the engine is first started. Honestly, you probably won't hurt anything in warmer weather, but if you live in a cold climate, you might cause some damage in bitter cold weather.
"Drove to a gas station and put in 2 quarts of oil......" Sure hope you let it sit for a few minutes and then checked the dipstick. Anything over halfway up the hashmark is over filled................What mileage is "30% of the oil life lost......" on the dipstick. Very possible that it's a considerable distance. NEVER gauge your oil consumption by an oil life monitor: Oil consumption is what a dipstick is for, period. "Life" is a very different parameter from "consumption" - the two have no correlation.
Yeah that is true but I was getting the message about every 1200miles or so and I am over that amount, I change it every 3k no matter what the Life says.
The guy said during an oil change most of this stuff will come out so that's why they say every 6 months because they figure about every other oil change. I won't put the stuff in the car again and I'll see what happens. Oil Change should be coming up next week.
Got the car in the middle of May and got it changed 1 week later...drove 3k in about 2-2.5 months and changed it.
So that was about the middle of July the last time I changed it, I should hit 3k in the next 1-2 days. I drive 3k in about 2-3 months. So that's about 12k a year I guess.
I believe I read that article when I was looking into buying a Caddy but forgot most the information on it. So its normal to have to add oil about every 12-1500 miles? I still have a qt of Castrol GTX in my trunk from when I added it the first time but I'll have to ask SpeeDee what oil they used so I can have that brand on hand.
I believe I ran it down to 15% when I first got the car and last time I changed it at about 39% because I was just over 3k and I was never religious about changing it in my Buick and Caprice and that lead to problems.
The system should tell me when to change it but is there a certain number it comes up at?
When the OLM determines that the oil/filter is due for a change it will post a message in the DIC. At that point you're supposed to change within a tank or two of gas. Go ahead and use your Castrol for top-up, but remember to only fill to halfway up the dipstick hashmark, cold. That's the full line, not the MAX at the top of the stick. There's a GM Service Bulletin on this - the engine burns off the first half-quart quickly when overfilled, and that leads to oil consumption complaints. 1200-1500 miles per quart is on the low side of acceptable consumption as published by GM/Cadillac. 7.5 quarts of oil with filter is the full mark, not 8 quarts as is common with jiffy oil change shops.
Curious about your OLM and a lot of driving - the more highway driving I do, the slower the OLM moves down, because highway driving is easier on the engine and oil than urban stop-and-go driving; under city or cold short hop driving conditions the OLM drops fairly fast.
Why It won't hurt it people prolly do it everywhere. They obviously do it at speede da de do or w/e the heck you where going to.
It calls for 7.5 correct. What does 7.5 put it at on the dipstick for the rest of you guys? I have seen it put it to max and on some put the level below half way. Halfway or right under on the cross hatch is ideal obviously and that's where I fill the oil to on the northstar. It's just others that add the half quart too much.
What we go by at places like jiffy lube is if it's not at the very top of the hash marks ppl will pull there dipstick after they leave and see it's halfway down the crosshatch which is technically safe on any vehicle but mainly they will come back and demand that we top it off the rest of the way (1/4 of a quart most the time) and then procede to say we tryed to not give them all there oil..... The N* is and exception with me and if the customer has a issue with it I give them the facts and they are happy and educated afterwards.
