I have about 15 litres of Mobil 1 5W30 sitting around and was going to use this in the summer for my 2002 Camry LE V6. I know at operating temp, the
10W30 and 5W30 are both 30 weight but the sheer strength may be thinner on the 5W30 grade. When temps run about 100 degrees F. or about 40 degrees C.. will the 5W30 cause issues with the engine where 10W30 won't? I mean I can always go and get 10W30 but given my driving (85% highway driving at 75 mph) and oil change frequency (every 7 weeks or 4,500 miles), I figure it should be ok.Any thoughts?
