How long have you ever gone between oil changes?

[xb visitor]

I'm a believer in synthetic I have always used 5-30wt usually Mobil 1 or a generic brand synthetic oil. I've had several vehicles that when swapped to synthetic the operating temps dropped about 10 degrees..So that convinced me to stay on that path.

I've done the majority of my changes at between 5k and the longest was over 11k, I live 2 hrs east of Los Angeles and ITS HOT where I live. HOT as in 120 degrees!! in the summer and 2 months over 100 degrees EVERY DAY. I drive my little car ..quite hard, Im sure I drive the poor thing FAR harder than most people here probably anyone..I'm not to proud to admit that, but its probably true When I changed the oil at 11k..IT WAS DARK, PURE BLACK IMO it was FAR TOO LONG, I also run a stupid "oiled" INJEN CAI air filter most of the time..it doesn't filter anywhere near as well as a stock filter does so probably attributed to the extremely dirty oil..

I'm totally in favor and recommend anyone to change the oil between 3k and 5k especially if you utilize a aftermarket "performance" filter. IMO there good for nothing but making a intake noise..unless you have a forced induction system or a modified cam intake set up.
I have 160,000 very hard miles and she's still running pretty good..no complaint. I do see metal particles in my oil changes. I might post another thread on this..I've been told its perfectly normal under any situation..so im on the fence over it.

I use to do it every 10 k. I do it 5.5 to 6.5 k now.
I am using Castrol high mileage oil for cars with 100 000 km and more.I change the oil filter and air filter every 6 months. Gearbox oil every 40k again using Castrol product called Syntrax with G70 gear box treatment additive.

Just so you know, it's not just 'your opinion'. Those filters do a very poor job of filtration. Cummins (diesel engine manufacturer) has come out with a TSB against them. Their capacity is lower than a stock cellulose and their efficiency is lower too. I'd recommend an AMSOIL dry filter to replace your oiled filter. We use the same filtration technology that our U.S. Government uses on the M1 Abram tanks. If you tell me what your filter dims are, I can look up an AMSOIL 'universal' filter to replace it with & give you a price.

I've never seen metal in my Yaris oil! I'd start a used oil analysis regimen on that car post haste before you get in position where the engine fails.

I have a Gold Plug http://www.goldplug.com/ in place, and there are metal (fine) metal particles stuck on it every time i change oil. Shouldn't be an issue, but you ARE looking at metal friction against metal.. there will always be some kind of metal particles falling off no matter what oil you use.
