engine oil substitutions?
I always use conventional oil when I do an oil change in my 2004, had since
new. Suddenly it has become very expensive. Can I substitute synthetic blend
oil without any drawbacks?
You can, just use the same weight oil that is recommended for your vehicle.
No problem. Change oil more often than with 100% syn. Shop Costco for high quality and cheap syn.
I used regular motor oil in my vehicle for years, the past year or so, all I could find in that brand was syn blend, so that's what I use. No problems as far as I know? My last oil change was the first time I used it.
