Could not changing the oil in 8 thousand miles cause severe engine trouble?

Not changing the oil and not having oil are 2 different things. Not changing the oil on those kind of miles will sludge up an engine in the long run leaving you in the same place you are now. Also not changing it, especially in cold weather will leave moisture in the oil and this is another engine killer. Many of the Saturn's are oil eaters. I have seen many them use a few quarts between a 3000 mile oil change.

It won't be severe if you have only missed a few oil changes... but... it takes life away from your engine. Engine oil lubricates and protects all of the moving parts, when the oil is dirty it will cause the parts to wear much faster. I've seen people who haven't changed their oil in over a year and it's black... I also saw a vehicle that didn't have an oil change in 5 years. The oil was as black as black can get and came out like tar, we took off the oil pan and it was just sludge. Not pretty. Take care of your vehicle and it will take care of you. People who get regular oil changes prolong the life of their engines.


Actually it is probably fine if all your trips exceed 10 miles and you don't idle to much. Most manufacturers recommend 7,500 mile intervals for highway type driving. I own an Audi Quattro Turbo and a 05 Bonneville GXP (300 hp Northstar v8). Both cars use Mobile one 0w40 synthetic oil. With the Audi I had used oil analysis done and found that 10,000 mile changes were fine and still had some reserve, could probably go 12k without issue. I have not done that on the Bonneville as that is my toy and doesn't get used much. I chance the oil when the GM oil life monitor tells me to. It varies from 4500-8000 miles usually because I have reached the one year requirement.

I summary I would not be concerned at all. If you are an average user with dinosaur oil than change it every 5k, synthetic 7500 unless you confirm you can go further through testing the drain oil.

The flashing engine light indicates a severe engine trouble code, for example constant engine misfire. If you pull the code with a reader, you will most likely pull up misfire on at least one cylinder.

yeah it will not be smart to do that you can get into major trouble, better yet you can face severe charges

I'm assuming you mean an ignition coil. If that is correct, an improperly functioning ignition coil will cause the engine to have a misfire, and could lead to severe engine damage if not corrected expeditiously.

when the engine cools moisture in the oil condensates in the oil dipstick tube. Some times changing the PVC valve will solve this. Unless it is severe then dont worry about it

You could possibly get in severe trouble yes.

Normally 80,000 to 100,000 miles. The owners manual will have this info. If it is an interference engine, failure to replace the belt at the prescribed time can result in severe engine damage. If you have no owners manual, call the dealer.

Depending on how much it is burning. If not severe just keep oil level full. If severe rebuild engine

On an interference engine the pistons will hit the valves and cause severe internal engine damage.

On an interference engine the pistons can hit the valves. That will cause severe internal engine damage.

Example sentence - I was quite apprehensive about changing medications after the severe asthma attack.

80k The above answer is incorrect. The belt requires changing at 100,000 miles under normal conditions. If you drive in severe conditions, then change it at 75,000 miles. Warning: This engine is an Interferance Engine and as such if the belt breaks serious engine damage will occur. Also the water pump is driven by the same belt. To save on future labor costs, replace the water pump at the same time you replace the belt. Considering the average driver is in severe conditions 90% of the time, I wouldn't say incorrect. Just a safe median.

No, but it can cause severe engine damage if you keep running the engine.

It depends if the engine is an interference engine. On an interference engine the positions will hit the valves and severe internal engine damage results.

The engine will overheat and can cause severe engine damage. The engine will be completely ruined if it is not immediately shut off.

A flashing check engine light is an indication of a severe engine misfire.

On an interference engine it can cause severe engine damage. On a non-interference engine the engine may not start or run incorrectly.

Pistons lacking in skirts. If it continues after the engine is warmed up then you have something more severe going on.

That is the check engine light. It blinks under a severe misfire.

No, this is an interference engine. You will have severe engine damage if the belt breaks.

According to the Gates website ( they make timing belts etcetera ) The 3.5 litre V6 engine in a 2000 Honda Odyssey is an INTERFERENCE ENGINE The recommended timing belt replacement is at ( 105,000 miles - normal , 60,000 miles severe ) * If the timing belt breaks you will have engine damage

Oil in the radiator indicates a possible severe problem, where coolant could also leak into the oil. Driving an engine in this situation at all could lead to severe engine damage.
