RVS Technology G4 Engine Oil Treatment, for Gasoline Engines with a Motor Oil Capacity up to 4 quarts; Save Fuel, Boost Power and Safely Restore and Protect Your Car, Truck, and All Other Engines

.:2005 Mazda3i approved:.Yes, yes, you! We all have come here because our beloveds seem to consume oil almost as fast as it consumes gasoline.2.0 fam, you know the deal.Rotary girls and boys, ya'll deal with it as well but for other reasons.Miata familia, listen up.2.3 crew, you know rod-knock is coming.2.5 club, ya'll don't really have to deal with this but follow along for the sake of sanity.I first purchased this because my 3 was running low on oil faster than I could catch it out of nowhere during a trip to Canada in 2018. It was driving great, I was ...well...taking flight BUT I started noticing the smell of friction (grew up around car guys and my uncles built many cars, so I got to know the goods and bads, and the smell that come along with it). I stumbled upon this while looking at something from Europe one day and also recently read about the dreaded rod knock and it's connection with low oil. Freaked out that it could be soon knocking at my door, I spent a good week looking at this product and looking for reviews. Not much in America was found at the time, but I said f-it and trusted it.The first application, I used to the T and noticed I was getting better MPG after the third day. Engine temperatures were something like 2 deg lower (I monitor everything) and overall it started to feel and drive better. I didn't want to judge too quickly, so I went ahead and changed my oil at the appropriate time and my MPG actually got better STILL. Very statisfied, I did another treatment almost a year later.Does my engine feel factory-new? No.Did my oil consumption get better? No.However,Does my engine get super hot? No.Did my MPG fade back to oblivion? No. It's still great!Does my engine operate great? Yes.Do I drive spirited all the time? Yes.Do I drive 3-4k rpm all the time w/ occasionally higher shifts due to cat/mouse in Me[x]ico? Yes.Do I drive more than 20-30 miles 6 days a week? Yes.Does my engine run like a champ? Absolutely.And because of that, i'll do the treatment as the guys of RVS Technology have mentioned.Is this a sponsored posting? No. However, if ya'll want to sponsor me, i'll gladly work with you guys! Lol.

I bought RVS now for my current BMW 435i that is highly modified and wanted to make sure my bearings, Turbo and engine is well protected. The car is low mileage (under 25k miles) but I wanted to have the best possible protection since I race the car occasionally so RVS Technology recommended I do a G6 treatment first and a G8 second. This is my 3rd car I've now treated and all have benefited greatly. My previous car (2009 328i)was dynoed before and after, and gained almost 10hp/15lbft at the wheels and on top of that gained 2mpg in fuel economy. Can't complain with that!

I bought the product based on all the reviews I had read. I was excited to use, but had to return because I bought for the wrong type of engine. When I’m able to afford I will by the product for vehicles.

I bought 2 box's of this for my fj cruiser.Fj runs great before and after. I really don't see any change in fuel or sounds or feel of engine. Not saying anything bad about product if it gives me super long life great.

I've now used RVS products in several cars and always with great results. This time I treated my Infiniti Q50 3.0T and wanted to prolong the life of the turbos and engine and the better fuel economy doesn't hurt either. Great line of products, highly recommended. My car is very low mileage, so I performed a G6 for the first treatment and then a G8 for the second treatment.

I originally used their Steering Pump additive, which I received great results with. Figured I would try engine additive and I am not disappointed. If you have a high mileage vehicle, you will need 2, as an oil change is recommended after 250 miles and another treatment needed.

If I could give zero feedback, I will do it. DO NOT BUY THIS PRODUCT. The reason I bought this for decrease my fuel consumption but after I use this product it decrease my fuel consumption. I usually get 21 or 22 mpg/gallon but after I use it it only get max 18 mpg/gallon. This is ripoff, I wish I can get refund for this junk

This stuff works! I get a few more mpg's and a bit more power. I can't afford to do a dyno test! HahaI was skeptical at first but bought it anyway and put it in vehicle now I'm a believer!
