started using Lucas Engine Oil 280,000 km. Presto!! 600 km goes up to 1000+ km per liter. Another 20,00 km and per km goes up an additional 200 km. Bonus. fabulous but not magnificent, but another bonus, fuel consumption goes down. Currently my 2001 Chrysler TC Ltd averages always 29-35 mpg highway and 16 mpg + city. What the heck, some 2019 van/trucks can't get that.. Zinga!! One day crossing from Calgary Alberta to Moosejaw Saskatchewan the old girl got 40 Mpg in that 700 km journey. Common now since then.

This is the first video of yours I have seen and I’d like to mention how much I like that your video does not have useless gaps of dead air or uninteresting filler video. You deliver the information quickly and effectively while having well edited cuts between camera shots. It works really well for my low attention span. Hadn’t realized I just watched nearly 8 minutes of video. Normally videos drag so much I lose interest after 30-45 seconds. Nice work

[@billybob677]

I used the lucas trany treatment in my 2001 f250 it smoothed out shifting . Good product

[@gaziger007]

I have used 25% Lucas Oil Additive in my 2001 7.3 diesel for over 300,000 miles. The truck currently has just over 400,000 miles. I recently had some repairs made to the truck and as part of the service the shop changed the oil. I knew when I picked it up that something was different. The engine was significantly louder to the point I could hear a couple of lifter clattering. When I got back to home base, I'm a full time RVer, I drained the oil and added a gallon of Lucas to 3 gallons of slightly used oil back to the truck. Sound dropped down to what I expected. I did have the oil tested and the primary concern from the lab was the increased viscosity of the oil. Since the 7.3 uses a high pressure oil pump for the hydraulic lifters I don't think the increased viscosity is that much of an issue. Well it hasn't been for the past 300,000 miles anyway. ;-)

[@clecollins2673]

I'm going to have a pull. Thank you sir! There are some bright people out there that give insight freely. God bless you.

[@hardball107]

Good advise Scotty, here another that has worked for me. Next time you run into a high mileage manual trans that is noisy, especially if it uses ATF for lube like a T5, change the oil and refill with a 10 wt. tractor/transmission oil compatible with wet brakes like HyTran. the heavier weight oil gives more cushion, it contains friction modifiers for high loads and will not effect any composite linings for the synchro's or whatever. I've used it in many vehicles from S10's to Mustangs with great success. Looks like a little STP shouldn't hurt either.

[@trroop17forever]

I used to use Slick 50 and Duralube in my old small engines. Seemed to keep them going a little longer.

[@lashlarue7924]

Great, video, Scotty! I couldn't agree more. Everything you said here is 100% spot-on. I'm ashamed to admit that years ago, when I was a stupid kid, I put a thick oil conditioner in a Lexus I had. Hydraulic everything. It didn't kill the motor, but the timing belt went out not long after that. Probably unrelated, but I still shudder to think about how stupid that was. Stupid is as stupid does.

[@Nonotkidding]

Thank you for the great videos. I have watched two or three dozen. I drive mostly freeway, and a little around town (Las Vegas, NV). Like you said, constant driving is ten times better than 'stop and go' driving. But I got a little carried away with specialty oils after the first 100,000 miles of using the recommended oil in my 2002 GMC Envoy. I changed it every 3000 miles. But from 100K to 150K miles I used synthetic blends, only changing it every 8,000 - 10,000 miles. And now that I'm over 215,000 miles, I'm using full synthetic oil, with a can of "Restore' and I've been going 12,000-15,000 miles between oil changes. I use the Lucas gas treatment with the better additive grades of gas, and I haven't changed my fuel filter since 50,000 miles. But in my new Dodge (I know, I know), I talked the dealer down from $43K to $19K, back in 2008, right after the economy tanked, and I only have 42,000 miles on it. I baby that truck for city deliveries and I use regular fuel, synthetic blend at the recommended viscosity and oil changes every 5,000 - 8,000 miles, depending on the weather, roads and amount of longer distance drives.

[@emergencylowmaneuvering7350]

Dirty oil needs to be out regardless how many miles. The dirt will clog oil holes and wear out will happen.

[@anthonydecarlo9694]

I love using Lucas additive, I used it for my 99 Tacoma begin at75k, sold it still running strong at 312k. It helps the dry starts in my tundra as well. I like that Lucas came with a newer product for these newer engines! Thanks for the video Scotty

[@markfarver2932]

Used the early thick Lucas Oil Stabilizer on a high mileage Triumph TR 6 FLAT tappet engine with piston slap at start up and the high cling performance stoped the engine rattle at start up. Good for older technology engines.

[@grant8064]

I put that oil stabilizer in the manual trans of my 1986 Isuzu Trooper II. Had what is believe to be a grinding synchro on 2nd, especially when cold. After adding that stuff it was pretty much gone.

[@bcgrittner]

Oh, yeah. Back in the old days I kept some of my old cars running with STP. The biggest problem was cold weather. STP was so viscous I could barely get those old engines to turn over. Would I use such additives in my late model cars? Not a chance. Thanks for reinforcing my thinking, Scotty.

[@user-nz6ss9sg7j]

Thanks Scotty I use reslone only in my 1978 Plymouth road runner. Original engine lifters no clacking

[@tjhessmon4327]

Most modern cars are constructed with very tight machining tolerances, and can take advantage of lubricants that have a thinner film at both cold and hot engine temperatures. Modern oil viscosity at 100C is 8.9 cenistoke’s cSt. Anything 8 cSt or above till lubricate well The Lucas Heavy Duty oil stabilizer is 110 cSt @ 100C, that is going to cause your oil pump to move a diluted oil that is several times its operational design pressure. The designations on your oil container indicate two operational conditions (cold and 100C or hot) Therefore, a 5W30, will have the thickness of a 5 weight oil when it’s cold and a 20 weight oil when it’s hot. @ 40C (104F) it will have a viscosity of 60 cSt @ 100C (212F) operating temperature, it will have a viscosity of 9-12 cSt @ -30 ( -22F) it will have a viscosity of less than 6600 cSt Yes most oil pumps can withstand a viscosity of 110 cSt, however, this will cause a loss in fuel economy, and will not repair most oil burning causes (worn piston rings, and or worn valve seals, and or stuck PCV). A thick sSt can account somewhat for worn internal engine mechanicals So adding an oil additive which has a viscosity of 110 cSt at 100C, can be very problematic, as it raises the cSt for both cold and hot engine operating conditions. As Scotty has indicated, it should never be used in engines with VVT, as the viscosity will be so high that the VVT assembly simply may not work, or it might become damaged.

[@DavidTMSN]

To expound upon that: How risky would it be using a 5w40 in a 5w30 only specified vvt tgdi engine? Newer car, but was curious about cold flow primarily.

Scotty I had a 2005 f150 that had 227360 miles on it. The trans was slipping bad I put the lucas stop slip in it and I ended up driving it for another 50000 miles until the cam phaser whipped out and snapped the cam in half. That lucas is some magical stuff.

[@alfredomarquez9777]

Oh yes... It is indeed magical WHEN people do not maintain their transmissions properly by changing and flushing the ATF at proper intervals... like at least every 40,000 miles AND/OR after a heavy towing ot tranny overheating incident...

[@robertkrause4861]

I use Lucas gas treatment in our 2012 fusions. Smooths then right out

[@uvilucatero9901]

Thanks for the great info. Love your easy going explanations. Lots of love

[@sithv6213]

Scotty, you answered an age old concern I've had for years regarding that Thick Lucas stuff in my 86 Regal Turbo with newer Comp Cams hydraulic roller lifters I installed. I've been blaming the lifter clack on the design of the lifters and cam.....but the Lucas thick stuff is probably contributing to the noise all this time! THANK YOU! I'll try the thinner stuff!

[@Johnny_from_RI]

Duralube brother

[@h8troodoh]

Or try the synthetic, it's much thinner..

[@user-mk7xv3ql5p]

Motion Plus. It's probably one the best oil stabilizers if not the best out there. Although you can't find it anymore in Orielly's. Probably because it works great on any gas engine or diesel truck engine.

[@harisyoung4110]

Molybdenum additive makes my 20years old mercedes noise gone and feel smooth like new..

[@bertgrau3934]

I have used Lucas in a 98 Chrysler with the 2.7 V6, 2001 Lincoln Town Car, and a Ford F150 5.0 V8. Not any problems, and it's made the engines run better with better gas mileage. And the Chrysler stopped using oil, and no smoking 170,000 miles. I have used a lot of Lucas products, and have had very good luck with them.

[@jesuslarsa4330]

Thanks Scotty, I need this for my Dad's Newer Model Toyota Camry. It burns a lot of synthetic oil between changes!

[@scotpence6709]

I like using Lucas oil stabilizer in my 1995 Silverado 5.7 tbi. It currently has 420,511 miles and still runs very well. The frame has seen better days though.

Do you use the thicker one or the thinner version....i have a 1991 chevy

[@gmoops8986]

Back in the day, if you had a burner change the 30wt oil and replace it with 50wt. It might help the rings to seal a bit better. It was still a band-aid.
