Brand new Nissan Armada PL 2011 First oil change after 5000 km What is better - regular or synthetic? If synthetic - what is the best?

synthetic is better because it is harder for it to brake down, especially at higher temperatures. Mobil 1 is a very good synthetic, so is royal purple. but i recommend using the weight that the manufacturer suggest on the manual. usually for new cars the weight of the oil should be 5w30, but check your manual to make sure. walmart usually sells 5quart jugs of mobil 1 synthetic for around 25 dollars, compared to autozone which costs like 7.50 per quart which adds up to around 40 for 5 quarts. hope this helps. goodluck.

Whats is the best oil to use for usage and miles out of a ford exp 2004 for the bang of the buck!

hands down synthetic oil is the best no contest versus conventional oil. i myself being a technician only use mobil 1 but you can also go with pennzoil or valvoline synthetic. castrol synthetic is ok but does not seem as good as the others and i have tried tried them all.

I have 72k on my Explorer. Which synthetic oil should I use.... full or a blend? Which brand is better and I change it myself. Is valvoline ok....

valvoline is fine,I would go with a blend because full synthetic really want have any benefits for you since you haven't used it from the beginning.I would go with a 10-30 blend then switch to heavier weight the more miles you have,make sure you change every 3,000 or 3months or more often in city traffic.

What type of synthetic oil should i use for my '99'BMW 323i

I just had my factory maintenance done on my volvo and the mechanic really likes the total (german) brand synthetic. he likes it better than castrol syntec

either this or use any brand name full synthetic.

I used 5w30 because I do not expect to be driving in temperatures above 86F in the next 5000 miles

Is it okay to change my oil early? And what is a good oil to use besides the recommended motorcraft? I am currently using Mobile 1 full synthetic

No harm in changing early and mobil 1 is a great oil, only once you use full synthetic make sure you continue to use it.

What type of oil should i use for a 96 mercury tracer

10/40. Full synthetic. I prefer Valvoline, all major brands have solid product though. Don't like the generic brands. Yeah is cost a few extra for the synthetic, but worth it. Change the filter. With higher mileage vehicles I also like to use a bottle of Lucas Oil treatment as well.

My 2000 gmc sierra is leaking oil on my driveway more than normal

It's not good to Switch back to Regular oil after using Synthetic. Use the High Mileage oil. It will help a Little. Still Cheaper to replace a Gasket or two than a Rebuild. Got 214,000 + Miles on my 95' Silverado and No Leaks with High Mileage Valvoline 10-40.
