I used 1.3 bottles for my M113 engine 3000mi ago. After pouring this product, I changed the engine oil. That was approximately 1200mi after pouring this product. Now I'm using MoS2 5W-40 without any leak stop, but considering that this product was in my engine at around 1.2K mi, can I add it again? or should I wait for 20K mi?

Yes, you can use it again without issue after 1,200 miles.

Can I use this with Pro Line Engine Flush? Thanks

Yes, the engine flush is to be performed before an oil change. The Motor Oil Saver additive can be added with the new oil.

Does this part qualify for lifetime warranty replacement?

Unfortunately, this wouldn't technically qualify because our warranty requires you to return the product. Once used, there's no way to actually return just the Motor Oil Saver.

Can this be paired with Mos2 anti-friction?

Yes, it can.

Safe to use on 2004 330 zhp Auto?.?

Yes, I personally used it on a 2004 330 ZHP and it seemed to help reduce oil leaks. Intended for engine use only.

Is this safe to use with MOL-LM20232 Liqui Moly MolyGen Oil

Yes, it is.

Is this product safe with valvoline 5w30 full synthetic xl-iii?

Yes, it is.

When can this be repeated after first used? You note "every oil change", but LiquiMoly says every 20K miles so overswelling doesn't happen. Which is correct??

Motor Oil Saver used every 20K miles would be sufficient to rejuvenate shrunken seals.

Can I add this to my engine oil even if it isn't leaking oil yet as a preventative measure? Thanks

It is a great idea to use as a preventative measure before you encounter leaks, we highly encourage it and use it as preventative maintenance here at FCP Euro.

Hi, can I put this into my engine oil with liqui moly ceratec?

No, use Cera Tec first, then this for the next 2 oil changes, then Cere Tec again and cycle like that.
