I was thinking today, it is a big pain in the *** to find 5w20 oils where i live, would it hurt my car (in anyway shape or form) to switch to 5w30? I have a 05 civic with some minor things done to it....

 

i doubt it, my buddy uses 10w30 in his lude

 

I have to ask where you live because every place that sells oil has 5W20, even freakin' Wal-Mart has had it for years. Its specified for a lot of Ford cars too. If you're buying oil form a mom and pop shop just ask Mom or Pop to get some 5W20 for you.

 

I just moved to Oak Island, NC and all the 5w-20 oil is conventional.....i went to auto zone, napa, walmart.....5w-30 just seems to be easier to use where i live.....

 

ya know i never knew my civic was suposed to use 5-20.... ive been using 10-30 since i bought my car..... i hope its not a problem... at least i havent felt any problem myself from using it....... i use it cause its for high milage mainly....

 

Have you tried eBay?

 

dont mean to thread jack but anyone know where i can buy synthetic oil for cheap online, tired off paying $7 for that mobil 1 or royal purple

 

I have only ever heard of using 5w30 that's what me, my stepfather (who owns a car dealership and uses on all his and his customers cars) my stepbrother, my father hell everyone i know uses and if it's not 5w30, it's 10w30

 

Not to repeat myself but would changing to 5w-30 hurt my car? because they only synth oil they have here is Royal purple XPR 5w-30. I asked the dealership....(i didnt give my name or anything) and they told me i not allowed to change my own oil or switch brands of oil....i immediately called bull **** on that......

 

To keep the warranty in force, you can use any brand of oil but it has to be the specified viscosity. It has to be labeled to meet the API spec required (like "SG"). You can change the oil yourself but if you don't keep meticulous records (such as receipts for the oil and filters, with the mileage and date noted), it will be very hard to get any warranty claim thru.

Autozone and Walmart here both have at least three brands of full synthetic 5W20 on the shelf. Not sure why it would be different at any of their other stores anywhere else in the USA.
