Can I use 5W30 in my 01 vw jetta gls?
Been using royal Purple synthetic 10W30 and seen most people have been using 5W30 or 5W40.
I'm sticking with RP just need to know if I can go with 5W30 ..Just let me know if I been using the wrong weight...I don't do cheap oil either
I'm in south carolina near the beach so it doesn't get snow here also.

Is switching types of motor oil (conventional, synthetic, etc.) harmful to my vehicle's engine?
Conventional, synthetic blend, synthetic and high-mileage motor oils are compatible and will not harm your vehicle's engine.
Thanks Apexxx, good info.
I'm just curious what I can run in my engine because I have a lot of oil laying around, namely 5w-30 semi-synth and plenty of Rotella T 15w-40.
Anyone ever use the 15w-40 in a 2.0 8v? It's thick but is it too thick for a northeast car?
15w-40 is what our BOSCH shop uses....in almost everything, inc Mom's 2.Slo Passat. It really will bog down the engine a bit, but it's usable above freezing.
You could always mix it down with thin oil, but it's really no big deal.
The 2.Slo will literally run on anything.
Just use the appropriate oil seasonally. You'll look forward to the 5w-30 after 15w-40. Not a bad combo.
