well i was just reading on another post that a guy used penzoil full synthetic 5w-20 and he said it was bad for his car and it scared me....i used castrol syntec 5w-30 on my car just yesterday...is that good oil for my car???i have 12,000 miles on it...thanks for any input...i'm not big on knowing oils and also i have a gen 5 camry se
^Yeah, its fine. 5w30 is the standard spec oil that Toyota uses for all of their cars. Personally, I use 10w30 because living in Cali, it doesn't get cold enough here for me to worry about my oil freezing. :lol:
From what I've read, Castrol Syntec is not a true synthetic, it's a hyrocracked group III, ie a highly refined/chemically altered dino oil (so says bobistheoilguy). Get some readily available Mobil1 in the 5w-30 flavor for winter(<10F) and 10w-30 for summer, it's a true synthetic. blah, blah, blah...If you do 3K mile OCI, just go with a good dino oil, no need for synthetic, unless you see temps of -20F in the winter...synthetic was designed for the extreme cold/hot, IIRC...I will say one thing, I use the Mobil1 synthetic for my 00 Solara SLE 1MZ-FE potential sludgemobile.
