After seeing one of my friends use this in his 3uz and watching this video I bought a bottle for $20 and it comes tomorrow I’m kind of sold what do you guys think?

 

VVT engines and oil additives generally don't go together. If you change your oil often an additive is not necessary and using any should be avoided. Oil additives may be applicable for some worn out oil burning engines. While changing your oil regularly should result in keeping an engine running long, if you have a car where oil changes were neglected and now the choice is to either try an additive or send the car to the salvage yard, why not try it.

 

the instructions say use 10% for everyday use or 15% for high performance use of total oil volume. I would think the thicker additive would mess with the vvt for sure they also say not to mix with Toyota oil, but bestline looks and moves like 5w30 I’ll take my chances but after watching multiple of those bearing videos feels like I’m extending the life of my car. It’s comes in a few hours and I’ll upload a before and after sound test to see if anything was louder or quieter than before

 

Engine oil may already be over 25% additives right off the shelf. Still have not found a recommendation by Toyota nor any other automobile manufacturer to use an oil additive. Most recommendations to use them may be by the manufactures of the additives themselves. A concern one may have with any oil additive is whether it will react negatively with the additives already present in the oil being used.

Have you looked into GF-6A oils? (GF-6A is backwards compatible with older engines) GF-6 oils are supposed to have better LSPI (low speed pre-ignition) protection, better deposit control, better gas mileage, and better performance. [Did post a question asking for feedback on GF-6 oils. But, no reply as of yet. Since ILSAC's (International Lubricants Standardization and Approval Committee) GF-6 oil standard is still fairly new, perhaps there may not be much in use yet.]

Hope all works out well for you.

 

I just poured it in did the sound clips but there was no difference in sound, I do use GF-6A penzoil platinum 5w30 this is my first run with it because I change my valve cover seals I ditched the penzoil high mileage oil

 

agree with you 100 percent

 

how do diamonds lubricate?

 

Like 90% of the aftermarket additives out there, this may well turn out to be snake-oil, but it may not.
In 10 years time all oils may contain this stuff, but I'd bet against it.
Engine lubrication is not just about reducing friction between surfaces as oil is also used for cooling and corrosion resistance.
As modern cars use all kinds of devices that a simple mower engine just won't use (oil filters, oil pressure driven cam adjustment, oil jets and sprays to reach certain parts) their comparison engine might as well have been a jet engine for all the similarities.

I ride motorcycles and about 15-20 years ago many of the oils started to include friction modifiers.
These friction modifiers ruined the wet clutches used in most modern bikes as the clutch plates no longer gripped when they should.
So, all of a sudden we had to check that the oils we used in our bikes did not have these friction modifiers in them.
Later on, it turns out some of them had PTFE particles in them and in cars and motorcycles these particles blocked oil ways and led to seized motors.
Some of the friction modifiers are still in oils today and work well, but many of them caused other problems.
Buyer beware!

 

^ Yea. Best thing you can do is just change your oil regularly, stick to the same oil and make sure pcv system is working right or install a catch can. If the engine is worn is already worn, nothing will bring back metal that is gone. All you can do is try a thicker oil to take up the slop.

 

I ran/run 2 ls's to 200 k miles neither used more than a 1/2 quart or rattled changing oil in 5-6 k miles. I never used additives
