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.
What causes a white substance to appear on an oil dipstick when engine is cold then when engine has warmed up the oil looks normal?
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…
What is the recommended mileage to cover after which one has to change ATF filter and transmission fluid for Subaru Forester?
There is no mileage where one "has" to change the transmission fluid or filter. It is your car and you can do with it as you wish. The warranty manual for my 2000 Forester recommends changing the fluid every 15,000 miles when used under severe conditions. I recommend changing ATF yearly and you shouldn't need to change the filter unless it has been damaged. It is as easy as changing the engine oil, so why…
Benadryl causes dry mouth and drowsiness or nervousness; Adderall causes dry mouth and nervousness - taking both might cause excessive dryness which can include a severe headache (your sinuses dry out too much) and trouble urinating (your bladder gets too dry); they might also cause severe nervousness or trouble sleeping.
What might be the reason for a 1998 Prelude to have a knocking sound in the engine when running but a lot of trouble starting or cranking if it starts or cranks at all?
Have you been getting regular oil changes? Always keeping up on your oil changes are extremely important, and failing to do so severe engine problems like these. I could ask if you are using premium gasoline which is required for Preludes, but they have knock sensors so you don't have to worry about that.
None for now. However, should a supernova explosion occur in our "neighborhood" (anywhere within a few thousand light-years in this case!), the strong radiation might have a severe impact on life on Earth.
