I buy 5 OE Toyota filters at a time from Amazon ( approximately $6 ea ) Purchase Ow-20 Idemitsu oil from NAPA ( ships free to my home ) in the cost saving 6gal box ( 24 qts ) for about $125 with their online coupon. Use this in both my Avalon and my Tundra- both run like a dream.

Pros: cars run like a dream, cost-saving
Vehicle: Toyota Avalon

I have a 2023 Civic Si.

I did every oil change at around 8k miles which is when my maintenance minder popped up, even though the dealer recommended every 5k. No issues ever, now at 46k miles.

Pros: no issues ever
Vehicle: Honda Civic
Mileage: 8000 km

This is normal. Wait till it gets below 1k rpm. Modern engines do not need a lot of time to idle after cold start, the ECU handles it. Although, for a few kilometres, do not push very hard. The engine oil (0w-20 idemitsu) is thin, and needs time to lubricate well.

Pros: thin, needs to lubricate

I ran 10W-50 and 10W-60 for a few years in an old and beaten up Honda in the hope of reduce oil consumption to avoid having to open the engine. Long story short: it's not harmful, it's an expensive gimmick, the only real-life effect is fuel consumption will slightly worsen and that Honda had occasional issues with VTEC (a well known issue in those engines when running high viscosity oils).

Pros: not harmful
Cons: expensive gimmick, worsen fuel consumption
Vehicle: Honda

I dont know about the newer 1.5t in the crv's, but im getting rid of mine because of the oil dilution issue. Sent out an oil sample and it came back with 8.2% dilution on oil that had 2k miles on it with 0 idle time. All the technical service bulletins have been done and \"nothing\" is wrong with the car.

Cons: oil dilution issue
