Rislone High Kilometre Compression Repair with Ring Seal is a concentrated proprietary blend of high-shear and premium polymers developed for higher mileage engines that are suffering from decreased or uneven compression. Low compression can be caused by normal engine wear and decreased sealing between the piston rings and cylinder walls.

Frequently Asked Questions

What are the most common causes of low engine compression?
Low compression can be caused by normal engine wear and decreased sealing between the piston rings and cylinder walls. This can be the result of scratches in the cylinder walls or sticking rings in the pistons which allow compression to move from the top of the cylinder down into the crankcase below the piston.

What are the signs of decreased compression?
Some signs of decreased compression include loss of power, poor fuel mileage, oil consumption, blue smoke from the exhaust, plug fouling and engine noise or vibrations.

What is Rislone Compression Repair with Ring Seal?
Rislone Compression Repair with Ring Seal is a concentrated proprietary blend of petroleum additives developed for higher mileage engines that are suffering from decreased or uneven compression. It contains a unique engine additive that repairs worn-out areas in the cylinder wall thereby restoring cylinder compression and improving engine performance to nearly new original condition.

How does Rislone Compression Repair with Ring Seal work?
Rislone Compression Repair with Ring Seal works two ways to solve low compression problems. First, chemical polymers work to fill in scratches and grooves in cylinder walls caused by normal wear, age and high mileage. Secondly, frees sticking rings in piston grooves to allow the rings to properly seal increasing compression.

    Sturdy solution
    Size: Standard--black
    I needed a way to mount rear speakers and this was the solution. They're sturdy and adjustable to fit reasonably sized speakers. They also pivot up and down and swivel so really perfect.

    Nice unit
    Set name: 5.1 Receiver
    I'm really happy with this receiver even though I don't have any speakers hooked up to it. Not using it for a speaker setup might sound like a waste of a product to some people but honestly I'm finding plenty of value in it with it's other features. The main reason I looked into getting a receiver was so I could have multiple hdmi devices hooked up to my monitor. I looked into hdmi hubs but there are a couple reasons why I've chosen a receiver instead. 1. Reliability and ease of use. Ok, so like I said I use a monitor in my room, not a tv. Monitors don't have remotes so anytime I want to change the volume or hdmi input I have to do it manually. It's a 32 inch monitor about 3 feet to the side of my bed and it's a nice arms stretch to do so. Not a big deal and while there are plenty of hdmi hubs that offer remote changing or automatic changing I worry about the reliability of those devices. There are plenty of reviews that state their hubs stop working after some months or the automatic hdmi switching starts changing inputs randomly or getting black screens and such. I just didn't want to hassle with things like that. 2. Bluetooth connectivity. This was another feature that I was looking into. Again, there are separate devices that offer this but just like hdmi hubs you will find plenty of reliability concerns. On top of that there's audio lag and previously when I bought a bluetooth transmitter I had to return it for that reason. Nice thing about this receiver is there is an adjustment for the audio to increase or decrease the audio timing but luckily it isn't an issue and the audio seems to be timed perfectly with my bluetooth headphones. It pairs up quickly too. I haven't tried the 4k upscaling with this receiver because I use a 1440p monitor but it's nice to know that it's there. Maybe in the future I will find a use for it. There's also some neat audio presets for things like movies, music and gaming. It's actually a pretty extensive list. I suppose I should also mention that each hdmi input can be named to your liking for a nice customization feel so when you flip through them you know exactly what's connected to that input. You can even use the hdmi ports when the unit is in standby mode but you won't be able to use the bluetooth connectivity. In the end I think this was a good purchase. It's priced reasonably and I'm getting good use out of it. Sound quality is great and the customizable features are a definite plus. More expensive than getting an hdmi hub and bluetooth transmitter but I think the reliability and extra features make up for this.

    Yamaha quality!
    Set name: 5.1 Receiver
    Excellent sound quality. Easy setup. Complicated audio menus take awhile to master, but once you do you'll be rewarded with amazing sound. Works flawless with my 4k projector and computer. 4 hdmi inputs handles all your audio and video. The auto labeling feature is amazing. I've been using it daily for two years and it performs perfectly. You'll need an external subwoofer amp which is a bit of a let down. I bought one of the small Fosi amps from Amazon that handles the bass flawlessly. Overall, an excellent receiver that will be the centerpiece of your audio and video system. Couldn't be happier. Buy it if you're on the edge of purchasing a new receiver!

    It's entry level but it does it great.
    Set name: 5.1 Receiver
    For what it is, an entry level reciver it is great. Haven't had it long now, about a month but it has been great. Used to own onkyo, pioneer and Harmon Kardon recivers back before HDMI and blu ray. Have used a soundbar for the past few years but finally decided to jump back on a detecated surround system. For my apartment this sounds phenomenal. I don't normally mess with the DSPs so I can't comment on those, I prefer direct sound. Could it use more power? Probably but again this is entry level stuff. I use 12 gauge speaker wire on the front 3 speakers and 14 to the surrounds and it sounds great. Front speakers are 6 ohms and rears are 8 but no trouble driving them. Dialog is crystal clear and the overall sound is warm and pleasant. Playback of Blu ray and Ultra blu ray in both DTS HD and Dolby TrueHD is such a treat, absolutely made me realize how limited a soundbar was. Music playback is fantastic, have my laptop with Jriver hooked up through HDMI for playback of FLAC and WAV audio files from 44khz/16bit all the way up to 192khz/24bit with every genre of music. Put it in direct stereo mode and it sounds blissful. DSD playback does work but only at 2.8mhz DSD64 which is still great considering the price. 4K pass through works as it should, no troubles with HDR or Dolby Vision content. Can't comment on FM or am radio playback. Bluetooth playback is alright, music enhancer does a noticible job of cleaning the music a bit, nothing extreme but does add a cetain clarity. The Bluetooth could have been a more recent standard especially since this reciver came out in 2018 but again entry level. For my Echo it is fine for the rare occasion I send audio to it. Playback of music from LG V60 over Bluetooth sounds okay but wired connection still beats wireless as far as audio is concerned and if you just playing back mp3s AAC, it won't matter, it works. 4K upscale works fine, really didn't mess with it too much because TV is normally going to do a better job of upscalling anyway. Has auto HDCP detection which is nice, allows all HDMI connections to play nice. Binding posts with Banna plug compatibility is nice to see at this price. User interface is nice and simple. One area I can see trouble with is the fact you have to go online for the manual. Again, as a entry level reciver there isn't really much to complain about.

    Nice for the price
    Set name: 5.1 Receiver, Set name: 5.1 Receiver
    Was extremely easy to set up. The automatic sound balancing works good. Sound quality is good as is the surround sound feature. I personally feels it loses a bit of sound quality when connecting a Bluetooth item like my phone. Otherwise, I am satisfied.
