Oil last forever but oil does get dirty. Synthetic oil like conventional oil does get dirty. You can extend your oil changes slightly if you synthetic oil but no more than two or 3000 miles.
Around 5,000 miles with conventional oil and 7,500 with synthetic.
a few seconds.
5W30 ....and synthetic or conventional is fine, synthetic is higher cost but lasts much longer between changes so the long term cost about evens out
Synthetic sleeping bags can typically last for 5-10 years with proper care and maintenance.
Follow the manufacture of your vehicles recommendations. Or change the oil/filter every 7,500 miles.
a long fcuking time! seems like hours!
Synthetic Mobil 1 oil last in sealed container has a shelf life of five years.
After opening and heating once how long does synthetic urine last
if you drive normally, mostly highway, and not in dusty conditions then I would recommend you change it every 7,000 miles. If you drive mostly city then every 5,000 miles. I do not recommend you use a synthetic blend. Either use conventional oil or 100% synthetic. With 100% synthetic you can go 8,000 miles.
Oil does not wear out it just gets dirty. Change it every 7,500 -10,000 miles if you use synthetic depending on how you drive.
