Engine oil additives

Does anyone like adding this kind of stuff to your oil changes? Is it really smart to add this on a high mileage taco like mine at 237,000 or is just fresh oil fine? I don’t know much about oil additives. I added a little bit of this hyper lube stuff on my last oil change and it ran absolutely terrible (surging while driving around 50-65mph) on my hour drive back home that same day. Though ran fine very next day and runs fine now.. What oils/ oil additives do you use?
Thanks

 

I Seafoam my engines a few hundred miles before oil changes to clean things out and I use LiquiMoly MOS2 in the BMWs to help lubricate the bearings. For the cooling system, Water Wetter works impressively well. A lot of these things are snake oil, if it claims to do anything incredible or magic it's probably BS.

 

When I bought my Tacoma new in 2001, the dealer carried this stuff called "MOC oil conditioner" so I would buy it in 6-pack form and have been adding a bottle at every oil change for the whole life of my truck. I couldn't find the MOC at Toyota anymore after about 2009 so I located a distributer guy in Oakland and bought 20 bottles from him directly. Being that this stuff is a sort of placebo since I faithfully change the oil every 3000 miles, it's more of a habit I formed in my own mind that I can't seem to kick, from when the truck was new.

 

Most of that old school snake oil shit just thickens the viscosity of the oil. Probably won't harm anything putting it in an old small block Chevy or slant 6, but there's no way I'd add it to an overhead cam. Modern oils have all the additives you need.

 

Yep, snake oil, IMO.

If this stuff was necessary, the manufacturer would recommend using it, but I'm not aware of a single car manufacturer that does.

If your truck has lost power/torque, you need new rings, seals, or a rebuild, not an oil additive.

Save your money: buy beer instead.

 

Oil additive doesn't make your truck run bad so if it did indeed it wasn't due to the additive. A good quality oil and filter changed on a regular basis is all that is needed. I always run Mobil 1 and Toyota filter. My 1st gen had 200k when I traded it in and ran like a top.

 

None, a well maintain vehicle shouldn't need any additives.

 

I did all kind of oil and fluids service with the BG products

For your specific question with over 200K I will for the engine these 2:

If after the cleaning you can do a full synthetic oil , then I will do 4.9 Qt. plus this ( 0.3 Q) (based on 5.2 Q that 3.4 engines requires) this will allow you to run up to 10,000 miles according to the blah blah ...etc below

If after the cleaning you just want to run Dino Oil and change every 6 months or whatever 5K miles , then I will do :

just my IMHO

 

I believe the bg products work for the rav4 when it had the burning oil issue. It was s tempt fix.

 

There are a ton of products out there that treat a whole grocery list of "symptoms". Use Top tier of the lowest octane you can run without pinging, change your oil and filter at a reasonable duration (everybody has their own idea of what that is, and thats fine) using the best oils available that fit into your budget and save your money.

I personally like using some Seafoam down the brake booster line every 10,000 miles but that's a personal preference and cant argue either way if it really does anything.

Like several people said above, if youre trying to clean up some sludge, change the oil after a short run often. A little varnish isnt anything to be concerned with.

 

If you've got a couple hundred thousand miles and your truck is running fine, you must be doing something right. The only thing that additives do is lighten your wallet. Older vehicles ran heavier weight oils, 10w30 or 10w40. If your truck is burning oil try running a heavier weight oil. Cause only an engine rebuild will cure that. Newer vehicles run a lighter oil to help get better gas mileage. Newer synthetic oils have better additives which prevent sheer and additives that provide better lubrication, especially under harsh conditions. IMO save up for that new Taco in another 200 K.

 

I add about 2 cap fulls of Gumout Multi-System Cleaner (because it contains PEA) into the oil of my Brigg & Stratton flathead lawnmower on the last mow before I change the oil. I NEVER add an additive to my vehicles. The lawnmower runs much more dirty, has loser tolerances, has no oil filter, can get hotter in the summer, and is in a much harsher climate than a vehicle engine. It might not do anything but my thought is it gets more yucky stuff suspended in the oil before it gets changed. Plus if it goes belly up, I get a new mower (current Snapper is 20+ years old).

Modern synthetic oil has everything necessary for your truck. You don't need to add anything. Change the oil when hot every 5,000 - 7,000 miles and you're as good as it gets.

 

Beer it is

 

Thanks guys I think imma stick to the 6k oil changes and that’s it
