I have an is350 and I lowkey just accidentally put 5 quarts of 0w-20 with like 1.5 quarts of 5w-20 on complete accident, both are pennzoil ultra platinum. Feels so dumb I was in a little bit of a rush and just grabbed 2 jugs from the same shelf and turns out one of them was 5w-20. Is there going to be any problems?( I assume not, I live down south so not super cold)
I just bought a 2014 is350 with 106000 miles clean title with mark levinson for 15k, good maintenance history 6k mile oil changes with 2 coolant flushes and 2 diff fluid changes in the history. Last owner drove like a grandma so never really driven hard fs. Getting a transmission fluid drains and fill hopefully this week since it’s never been changed before. Doing an oil change (pennzoil ultra platinum with oem Toyota filter), air filters, cabin air filters and spark plugs. I do want to know if GSF lcas were worth the time and money to do, I really don drive the car extremely hard, especially not aggressive canyon driving. This cars drives really good, mostly because I am coming from a complete base model rx350 with 230,000 miles super blown struts warped brakes and cracked lower control arm bushings. Any tips? Thanks
