No problem mixing oil brands.

 

:yeahthat:Mixing brands is ok, but mixing weights is bad

 

so what makes u like mobile 1 over royal purple i luv the purp and curious to y u like mobile 1 better

 

thanks for the info!



I'm just your average car owner, really, but to me... the additional cost of Royal Purple wasn't worth it. It burned more than any other oil I've tried in the Si. The 5 quarts I bought didn't even last 5,000 miles before it was due for a change. Smelled pretty bad without a cat, too; worse than other oils.

I ran Mobil 1 synthetic in my '97 Civic for around 9 years, and over 200,000 miles, and it was still running strong when I traded it in! So consider me a Mobil 1 fan

 

i mix occasionally. just make sure you get the weights right.

 

i know this sounds kinda silly but did u take into effect that purp starts out alot darker than the clear mobile 1? i havent really noticed anymore burning on my oil that would make wanna change it sooner or change brands and im pretty hard on mine espescially since i just put on my sk2 76mm exhaust i cant keep my foot outta it but thnx for the response i like hearing other people opinions it helps us move forward

 

Oh no, I don't mean burning as in the color of the oil, just the way the oil level degraded over time. I don't recall driving any harder than usual with Royal Purple, and I'm rarely in VTEC. The smell during warm-up and the cost factor were my main reasons to go back to Mobil 1. I'm a broke college student; can't afford $60 oil changes every three months

There's a member here who was doing ~12,000 mi. oil change intervals, and having a sample sent out for evaluation. He made a thread for each different type of oil he had evaluated, not sure if he ever tried Royal Purple, though. Definitely worth finding the threads if you're interested in any other oil brands. I do remember him speaking highly of Pennzoil Platinum as an inexpensive, great-performing synthetic oil.
