Considering that most oils on the market are not that great to begin with, and the fact that we probably all drive our cars harder than grandmas churcher, you should probably not worry bout the $3 saving you will get from extended interval changes ;)

In other words, keep changing your oil at the recommended interval regardless.

If the oil contamination is much less,why still pursue the same regime?

I have read 20,000km plus for oil changes for those on LPG . I have no experience but I always like to check information from those who have.

Given synthetic oil costs and

oil filter costs ( without labour costs and the inconvenience of finding time to have an oil change) you

could easily be spending an additional $ 350 extra if you

change your oil at 5000k intervals instead of 20,000k.

petrol contamination is only a small part of what happens to your oil while your motor is running... oils lose viscosity over time, cleaning additives stop working and froth up, things like that arent just contamination. i guess heat cycling and running it through a pump constantly must take its toll in some way too. i'd suspect its the people who sell/install lpg that will tell you its a miracle fuel that prolongs service intervals etc

i'm no expert so take what i say with a grain of salt :P

never failed to surprise me how clean the oil stayed in my lpg work falcon . the thing did over 200 kays a day . every week . bout 50 kays a day was offroad in subdivisions. once got to 30-000 over the oil change and it was still clean .

    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
    • You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
    • Thanks for the quick reply. To be clear, when you say turbo shuffle do you mean turbo flutter "stustustu" or referring to something else? I had thought they were the same thing. When I wrote the post my intention was to say it wasn't a flutter/compression surge sound. My understanding was that a flutter sound would be occurring when throttle is released, whereas I can keep the throttle in the same position for this noise
