OK, the RAV4 Prime is Toyota's second Plug In Hybrid Vehicle (PHEV) and has about 45 miles of battery only range. Thereafter it switches to Hybrid vehicle (HV mode) since it "saves" some battery to allow continued hybrid use, in conjunction with the A25A-FXS atkinson cycle 2.5l NA 4 cylinder...

Well, I have a new Rav4 Prime (PHEV) and they have a habit of turning on the gas engine for a minute once in a while. If you can charge your battery, you can drive nearly 100% of the time in EV mode, but there are reports of drivers that seldom drive long distances with the gas engine running...

Hey folks, all this reading about brake fluid has me thinking that I should change my ways a little and put fresh fluid in my vehicles a little more often. But I am always a one man operation. Saw speedibleed system mentioned in a couple posts. I have mostly toyotas (Prius x 2 and a new RAV4)...

My 2011 Prius is headed a long long way away with my daughter and I doubt she will ever flush the brake fluid. I have tested the fluid yearly for moisture and its always been dry, but now, with the vehicle setting sail and probably will not be driven home again, I am planning a brake fluid...

Well, I've been a bad boy and haven't paid much attention to state of the art, but I do know that they continue to change the oil formulation and what is good for my 2020 RAV4 would probably cause my 65 to throw a rod in 20 miles. I've not changed the oil in the 65 for several years (it gets...

Did a fluid change on my 04 Expedition yesterday. 164k on the original fluid. It looked OK on the dipstick, with no bad smell, but in the pan it was pretty dark. There was some fine ferrous sludge on the magnet and a good number of fine bright non ferrous flecks that I could see in the sunlight...

I cannot bring myself to let the dealer do a power flush on my 04 expedition with 164k miles. I just have too many visions and stories of that power flush stirring up filings and crud that was safely sitting in some corner not bothering anyone... But the fluid has got to have lost some of its...

Just one personal observation, based on the last few weeks driving. I commute with a pretty predicatable route/combo of drving and temps. Decided to put some 0w20 Mobil 1 in my 2006 1ZZ-FE Corrola to see if it would have better fuel economy than the PP 5w30. I commute about 17 miles, but there...

OK, I think this has been discussed in many threads before, but I'd like to ask it again. My engine, like many, calls for 5w20. I'd like to see what happens to the winter fuel economy with 0w20. The vehicle sees mostly cold starts and short trips. OCI will be 5k or less (Oct 1 to April 1...

I am putting a C4 behind my 240 I6 Ford. Will not get raced or deliberately abused, but I may tow on occassion. Its a mild build, no fancy clutches etc... I will probably keep this truck until I die (Dad bought it when I was 6 months old), so I look at things with a LONG time frame. Money is...

OK, new Kia 3.8 with solid lifters (seems like these are increasingly common on new engines.) #@$%!, my 240 I6 was Fords revolutionary six engine with hydraulic lifters -- its been going for 40+ years. But I digress. The KIA potetially needs some serious service at 60k if those lifters need...

Well, I have decided to run PP in my two vehicles. Decided to run 5w20 in winter and 5w30 in Summer. Long story. I have excellent UOA from the 5w30 PP on my 2006 Corrola already. Hope the Kia follows suit. But both vehicles spec or allow 5w20 as well. But that's not the question. Money is not...

Per Toyota TSB, there are now putting 5w-20 in many of their engines, and have adopted it as their "Toyota genuine engine oil". ILSAC GF-4 in all cases. The same TSB notes that some engines (Prius I believe, with a 2AZ-FE engine) can have 0w-20 GF-4. Why should an engine that can handle 5w-20...

I have visited several AZ in the KC area and they are all not carrying GC. Moreover, the managers look at me like I am from Mars when I ask for it. But one manager said if I could find an Autozone part #, he'd be happy to look it up and order me some, if it really exists. (maybe this whole...

OK, new engine. Brand and engine are largely irrelevant for this question, but if you must know, its a 3.8l Kia in a Sedona. Manual recomends to avoid high speeds, hard breaking for first few hundred miles...... Popular lore says to avoid "prolonged driving at same speed". Many folks all over...

OK, thanks for reading this post with that cryptic subject line for starters. I have bought a 2006 Kia Sedona with a 3.8l v6 DOHC engine. Its a new engine for Kia, Hyundi too. Going to be used in a bunch of vehicles, has VVT etc. Great torque and decent fuel economy for an engine of its size...

OK, this a new Toyota Corolla. I ran the original oil 2k miles, then switched to Penz Platinum 5w30 for the next 3k. UOA Shows the following: copper 66 Silicon 66 Sodium 38 Magnesium 17 Calcium 1759 Phos 686 Zinc 817 Moly 49 Visc at 100 9.4 other numbers are negligably low. (Iron etc.) Cenex...

OK, 3.3l V6 in 97 Dodge Caravan. Started using some oil, about 1q, every 3k, at about 70k miles. Hard miles, similar to taxi cab. Has some leaks and smudges, but no puddles on the floor. Passes inspection. I tried M1 5w30 EP -- oil use was the same and a faint rattle at idle (local mech thinks...

My 3.3l dodge V6 has about 80k miles. Of late, its been burning a quart of oil every 1800-2000 miles and when the engine is good and hot, I can hear a tapping at low rpm. I have been told that "tap tap tap" is lifters, but I am no engine guru. It sure weren't there orginally. The oil gets...
