Oils aint oils
G'day guys,
Just out of curiosity, how can you tell if engine oil is bad or not?
I'm in the middle of changing the oil in my car after having it for a few weeks (had car yard service but don't trust them) and was interested to know how you can tell if your oil is clean or filthy?
I'm pretty sure I was low anyway because it's just about drained (just slowly dripping) and my drain tray is just under 7ltrs. I should have 8.8ltrs, is that correct?
Cheers
Ok here's the skinny.
If is black , it's bad.
If it's brown it's bad
If it's white, it's really bad.
If it's black, brown or Pink for that matter with little bits of metal in it, start saving :bananaro:
If it's golden like honey, that's goooood.
If it's full of Sh*t run an engine flush through it.
When you change your oil , change your oil filter.
Depending on where your drain plug is situated, jack the vehicle up so the more oil can drain out. Leave it for as long as you can with drain plug and oil filter out, it take ages for the top oil to drain out and you'll never completely flush it all.
If it's really dirty buy some cheap ass NEW oil and put it through the system before your put your expensive stuff in.
Warm up the engine before you drain it. The oil is runnier when hot. Be careful not to burn yourself.:eviltong: I said warm NOT hot.
Fully Synthetic oils are ACE but your car might not like them

. Cars that have been running on Mineral based oils all there life crack the sh*ts when you try to run them on fully sic synthetics
When you can get around to it Change every other liquid in your vehicle as well, especially if it is old.
Transmission oil, Front and rear Diff oil (Esp if U R doing a lot of water crossing), clutch and brake fluids, radiator flush and cool ant
I like Iridium spark plugs only need changing every 100,000 klms. Air filter and Petrol filter unless you have a diesel and your done.
