Going from memory, but the station where I get ethanol has 5 blends (10-20-30-50-85) and one hose. I typically get E-85 due to the cost. Often, I’m adding E/85 to a tank half filled with regular unleaded.

Found an old bottle of Havoline 20W/20 on the shelf of a store I worked at several years ago.

Personally, I think high mileage that what constitutes high mileage is going to vary by engine. 75k miles on a 4 cylinder probably isn’t the same as 75k on a 6 cylinder. 75k on a 6 cylinder isn’t going to be the same as 75k on an 8 cylinder.

My 2016 Dodge Grand Caravan 3.6 is starting to get engine tick from the rocker arms, presumably. Is there a particular brand of rocker arms that would be more durable than the others?

Has anyone used 505 CRO (oil additive) and 505 CRF (fuel additive)? Is used to decarbonize the engine.

2007 Buick Lucern. Low tire pressure light comes on intermittently and we get the message “Service Tire Monitor System “. We s this just a tire pressure monitor or something else? Can it be determined which tire pressure monitor?

See above “in spite of my admonishons and protestations “. These were verbal interactions wherein I tried to impress upon her the importance of checking her oil. Including explaining how metal objects like pistons, rubbing on other metal objects like cylinders, cause friction, heat and...

Nope!

Well, in the case of my daughter’s vehicle, it is better to use these products and have something in the sump than to pull the dipstick and have nothing showing. This has happened several times in spite of my admonishons and protestations! I check mine regularly enough to perhaps get by with a...

In a normally functioning engine, or one that was worth repairing, I would agree. It’s a matter of mitigating a problem, if possible, in a low, cost effective manner if possible. Perhaps just running thicker oil wil solve the problem. If the additives don’t work, I’ve learned what not to do...

2016 Grand Caravan. 160k miles. 6 qts Havoline HM Full Synthetic. Proselect filter.

I did go ahead and add the LubriMoly Motor Oil Saver. Figured I will run until time to change then go to 10W/40 or 20W/50

It’s a 4.3 V6. The stem deals were replaced. Replacing the stem seals, combined with bad valve guides, seemed to worsen the problem; for whatever reason. Prior to replacing the stem seals, the compression was checked and was good. All cylinders checked within the 140-170 range. The vehicle runs...

I only put 6k miles per year on this vehicle. I change every six months since the odometer broke.

The Lucas has drastically cut the consumption. Barely any oil loss in six weeks.

I’ve tried Restore on other vehicles in the past. Wasn’t sure if it would help with bad valve guides. I emailed Restore some time back and didn’t get a reply. May give it a shot. Would much rather have Restore in my engine during the winter months than Lucas.

Took it back and exchanged it. Checked the bottles. No other misprints.

Because Wal-Mart caters to the Mexican populations in the US. In Colorado, the aisle markers are in English and Spainish.

I actually need 10W/40 for my application. I have bad valve guides and was using a lot of oil. I changed the oil 5 weeks ago and added a quart of Lucas Oil Stabilizer. No oil usage in 5 weeks. Others have said Lucas is garbage and suggested that just a thicker oil would help. I don’t necessarily...

Quaker State was no real help. They just said to return it to Wal-Mart. He asked for the UPC code. I provided him with that and he said that it is 10W/30. I explained, again, that the front label says 10W/40 and asked “How do we know if the back label isn’t wrong?”. He didn’t have an answer. My...
