Hi all,
I would like to know if anyone has any good or bad experience after engine flush.
Driving Toyota camry 2009, service due @180,000.
have done all the oil changes according to the logbook, thinking to do by myself this time, but not sure if I should use (Liqui Moly) engine flush.
Thanks in advance.
Sorry Jimbo don't agree. Our 2007 diesel Pajero has 318,000ks on it and has had engine flush every oil change. The oil and filter are changed every 7,500ks.
Engine flush gets rid of the gunk before it turns to sludge. Take the oil filler cap of and see if it has just oil on it or the build of of gunk or sludge. You can also run your finger inside the hole into the rocker cover and see if that is clean.
I would use Nulon engine flush It's a good Aussie company. Make sure you read the instructions as there are different types.
Don't buy cheap oil or oil filter. There are many many brands on the market. Ryco would probably be your best bet from any of the auto stores. We prefer not to change the brand, grade or type of oil we use. Been using the one brand, type and grade for 313,000ks.
It's a bit late waiting till you have noises. Preventative maintenance is the way to go.
All that you've claimed doesn't prove is the result of using an oil flush.
Besides ,the manufacturer doesn't recommend a flush to be used.
Correct sidewinder. There are also plenty of Pajeros running at over 300,000km that have had an oil change less often than every 7500km. Not saying it isn't necessary, nor that it hasn't improved the lifespan of that particular engine though.
Well, I agree with annandale. Sure you don't have to, and modern car handbooks say you don't need to let the car warm up. Of course, letting a car warm up is definitely better for the engine. Many enthusiasts believe that this practice by manufacturers is to keep fuel consumption down - make the car look more economical. So I could imagine that if one manufacturer recommended engine flushes, people would go with a car that didn't need an engine flush. It is a potential issue; more so with diesel engines. If I had a diesel and it was aging, I'd consider it
Yeah ok, here's one for you. People tell me I'm crazy because I have a special rock in my garden that keeps tigers away. I say it must be working as I ain't ever seen a tiger in my garden.
Is the logbook saying you need to do a flush?
Do you have any reasons to believe you need to do a engine flush?
Yes, the engine flush company's marketing team have determined it is necessary. Note, occasionally the marketing team have been approached as to how to market snake oil.
You know there are valid reasons for a engine flush, so drink you're snake oil and learn.
Of course, but the marketing team have led people to believe it is routine maintenance that you do with almost every oil change. Unless your manufacturer recommends it, or a trusted mechanic recommends it (ie not an upselling dealer 'mechanic') you probably don't need it.
@Euphemistic: So as I said then in the FIRST comment……
Is the logbook saying you need to do a flush?
Do you have any reasons to believe you need to do an engine flush?
TL:DR option: just leave you Camry alone, it will work forever if you take it easy and do just what the service manual says:)
All quality engine oils will already have the cleaning agent as part of the mixture. There will be just right proportion between cleaning and lubrication function in the oil.
Engine flush will certainly do the cleaning quicker than any engine oil, however you will be sacrificing the lubrication component for the period when flush is used. This cannot be good for your engine.
Also - you would not be able to flush your engine flush entirely from the engine after flushing (ha-ha-ha here). Therefore your new fancy engine oil will be diluted with the engine flush and has worse lubrication qualities until at least the next oil change.
You need to use engine flush flush for that.
@ andyvolk.
Our Pajero as stated above has engine flush every oil change. So far it's on 318000ks and had 47 oil changes. How long do we have to go before it is no good for our engine?
I've always changed my own oils. Replaced the filter each time. I use synthetic, which is quite thin. If you change oil at fairly short intervals it I think it is OK. For example, I have a terios 1.3 litre that I change every 5,000km because the engine works quite hard. I drain the oil after I've been driving it so that the oil is thin and all the contaminants are suspended in the oil. Hopefully it all comes out. If it was an older 2nd hand car, especially a diesel (they get dirtier), and I thought the oil changes were not that frequent, I'd consider flushing the engine out with diesel fuel. This is what used to be used before 3rd party companies thought it had to be value added to justify paying more. The theory is that diesel fuel is also a light lubricant. https://www.youtube.com/watch?v=kK33EHlk_M0 I have heard of oil lines (internal pipes that transport oil to different locations in the engine) being blocked with crud. I suppose if an engine was sitting for years this might be another cause of that. I suppose I'd look at it as declogging the arteries - you want oil to get where it is needed. As previously mentioned, if you were worried about contamination of the new oil with residual diesel, just go a slightly heavier oil ie if it is normally 5w20, go 10w30, or go half and half should be more than fine, even just a litre of slightly heavier oil; the residual diesel would really be minimal
If you flush it, u better also remove the engine sump and clean the oil pickup.
Wouldn't that get cleaned during the flush and subsequent drain?
Thanks guys for all the opinions.
Reading through comments feels like not many people have experience with engine flush. Mostly everyone is commenting about how bad it could be, not sure if they heard from someone or watched on the YouTube.
Is there anyone who has done the engine flush? or does it make everyone worried that what it might do to the engine.
Last 3 service on my Toyota Camry were done @15000KM intervals, as per manufacture stated in the book.
Mate I have already posted this but as you probably didn't read it here it is again.
"Our Pajero as stated above has engine flush every oil change. So far it's on 318,000ks and had 47 oil changes. How long do we have to go before it is no good for our engine?"
Really you should do what you want to do. Your choice.
Thanks annandale. Sorry must have missed from the comment section. what type of engine flush you've been using?
Wynns or Nulon. Whichever is on special at Supercheap. Please follow the instructions.
I think it's more that the comments are more about whether it actually does any good, not so much that it does harm. IMO the only harm it does is to your wallet. There may be slight benefits, but regular servicing (in accordance with the manufacturers recommendations) should be enough to keep and engine running well for the life of the car. An engine flush probably won't do any harm, but it might not provide enough benefit to be economically viable.
One person saying that they do it every service doesn't mean it is beneficial. That engine may well have been running just as efficiently with the regular oil changes without the flush.
Its pointless if you've had all the oil changes on time and don't have any issues (ie. odd noises).
