2005 Dodge Ram 1500 SLT 8 Cyl 5.70L
my truck required 5w20 motor oil and I added 5w30 by mistake, will this make a differance since it is warming up outside
owners manual states for 5.7 hemi engine should use 5w20, for the 4cyl. and 6cly. you use 5w30.
No difference and will cause no harm. Change to the correct oil next oil change.
