GV is starting to get a little noisy in the engine so i thought its time to do a full flush and oil change. What engine flush do you all recomend. Ive been told some just dislodge the crap and that can lead to it blocking up other parts of the motor. Are there any that disolve the sludge.? Any better than others? Cheers B4T |

Diesel oil is a good flush, the only real diff is it has more detergents, so, will flush well. Use same grade, alls well. |

Its a shame a lot of mechanics these days need 4 years to learn how to change oil and brake pads and don't take in any of the why of a subject and then form opinions based on no knowledge. as long as the oil you are using has a spark ignition engine rating on it (will say SG, SF, SH, SI something like that) probably near its Compression ignition engine rating (C something) then its perfectly fine to use, infact the extra detergents in Diesel oil are probably helpful |

I know a few guys that use diesel oil in big bore and turbo busas with good results. I use LPG oil in mine and it seems to work well. |

i've used the nulon engine flush for the last 12 odd years, always change my oil @ 5000kms & the oil goes from being a nice honey gold colour to being as black as the ace of spades once it's been added & idled for 10-15 mins |

I've got a mechanics book from the 1940s that says when you drain the the oil you should fill the sump with diesel and let idle for a few minutes, drain the diesel out then fill it with proper oil. I put black and gold oil in the LJ. It hadn't been serviced for 16 years or something, the old oil was like black paint. The black and gold went black pretty much strait away but it went from being black under the rocker cover to exposed alloy. What ever the Black and Gold has in it, it eats sludge! |

How dirty is the engine. For really bad engines I put 4l of diesel in with a new filter and let it run for a few min with some revs. Drop the fuel out, another new oil filter and fill with oil. On diesel oil in a petrol engine, I have don't it for the last 10 years and never had a problem. 1st oil change will be dirty then it gets better. Ran diesel oil in everything from pit bikes, cruisers, sierras, vitara's, kingswods with striker engines, range rovers, xr6t's, commodores. Every time 1st change is pretty dirty. |

I tend to run a thicker oil in every thing. 20/50 or 20/60. Then you never run to thin a oil and kill a bearing. You might lose some hp but it would be like 1-15 hp depending on the engine, it's not a race car so who cares and it's only a proof tenth between a 0 weight and a 20 weight on start up. Put it in perspective I ran a 20/60 penlight in the last 2 turbo xr6 and most people run a 0/40 fully sin oil and change it every 5000k because its going dark. With the diesel oil I was leaving till 7500k till I changed the oil, came out golden on a fat tune with extra boost for more than 50,000 k till the wife wrote off the 1st one.2nd xr was a lemon so only put about 10,000 k on it before we sold it. I'm about to put the same in the ve ss because after 3000k the oil is getting dark and in my opinion wouldn't make it till the next service at 50,000k |

Thicker oils can create problems for you - if the engine has hydraulic lifters or self adjusting hydraulic timing chain tensioners - the GV V6 has both - you can run it if you want, I wouldn't. You may feel it's only a "proof tenth" thicker at start up, but, my ears tell me it's the difference between lifters that rattle at startup and lifters that don't. |

Been out playing with the GV and ive noticed the engine noise is quiet at start up but gets noisy after about 20sec of running. Oil is Nulon 10w40. It's only 3000kms old and is still nice and clear on the dipstick. |

Done this on my old 2.8 Rodeo when I 1st bought it. Drain....add 5L diesel....idle for 5.....drain......5L fresh oil...run for 5...drain....new filter and fill with oil.....change oil and filter again after 1000k. Ended up getting and extra .5 - .75L of oil in it after doing that. |

Done some research into this and alot of the premium oils out there are suitable for both Petrol and Deisel motors. Penrite oil is one thats for both and thats printed all over the bottles. |
